blew it up!!!

[ZR1BLAZER]

well i think i figured out all my tuning issues. i took it out tothe street and got the sucker to smoke em down. i pulled back in the driveway to adjust the timing a little more, took it back to the street and POW blew out the rear. i think i am going to strip down and put the 4.3 from the 92 in it and just drive. i think i will sell everything and start a new project later when money allows.

[carkiller]

YOUR SO CLOSE......dont give up now http://www.s10v8.com/images/smilies/icon_smile.gif a few more bucks and you will be MUCH happier http://www.s10v8.com/images/smilies/icon_wink.gif

[ZR1BLAZER]

if i blew up a rear that has all new internals built by a professional an damn near 0 miles then the only thing i can do is slap in a 8.5, 12 bolt or nine bolt and i dont have the extra cash to do any of them. work has been real slow this year.

[DMONOTJR]

DON\'T DO IT DAYNA! think of it as you and your son\'s first buildup. don\'t give in to the lil evil ford guy on your shoulder. listen to the nice and all powerful chevy guy on your other shoulder and fix it!

[Indiana]

Put a stock rear back in and don\'t beat on it.

[FordWizKid]

Man that sure does suck... but I know how yah feel. My truck got broken into and they stole about $2500 worth of parts. I put it up for sale and recently decided to finish it instead. Don\'t give up now I\'m sure you have a sh*# load of time in it !

i was thinking about just taking the rear from the 92 because the 92 is to far gone to rebuild. and just put in mine. but its the same rear that was in mine except i had a posi and 4.56 gears put in. i have never really beat on it because i have never really drove it. so if power breaking for 30 sec or so on a half tuned motor did that kind of damage then i will completly destroy a never touched high milage 10 bolt just driving around. and if i have to just drive and never have fun with power then whats the point in having a v8 in the S10? i can have fun with a vortec 4.3 with a carb and not break anything.

I\'m thinking that your rear was NOT right to begin with. Power breaking won\'t hurt even the crappiest of rears. Shock breaks rears. I\'d put a stocker back in, as everyone is suggesting. Then as time permits look inside to see what broke. Then, I\'d have a talk with that \"professional\" who built the rear.

....... I\'m presuming you didn\'t have on slicks or sticky tires? No way a rear should break with street tires.

[ZR1BLAZER]

they are drag radials but i agree. that dont mean shit on the street power breaking. when i pull it out i do plan on looking at it to see if i can tell what happen. the axel on the driver side is trying to come out just pushing it back in the drive way. my son said that only the pass side tire was starting to spin when i heard a snap and the motor reved. it sounded like the drive shaft but it wasnt. i set the parking brake and put it in gear and the shaft was spinning and the rear was making all kinds of noise? i dont know what to do i am just pissed and discouraged all at the same time. but i am real close on the motor http://www.s10v8.com/images/smilies/icon_smile.gif it wouldnt even spin the tires in the rocks before. you think maybe if the rear was set up wrong that this could have something to do with how shitty it drives?

[Knanthrup]

Sorry to hear buddy.



I would seriously just throw in the other stocker rear and take it easy on it. Put street tires on it no slicks or DR\'s. There really should be NO way you break even a stock rear power braking it. I\'ve seen guys put much more abuse to them than that.



Dunno what happened but I would seriously talk to the guy who built your rear and find out whats going on. Maybe you can get him to put it back together for you since he most likely did something wrong in there.



Good luck, hang in there

[FordWizKid]

Sounds to me like you busted your spider gears. What kind of diff. are you using ? I have my rear built with a clutchless diff. from a SS camaro so there is no spider gears to break technically. I am running a NV3500 5 speed with 3.73 gears.. I put a stock clutch in hoping if something was gonna go it was gonna be the clutch...

[ZR1BLAZER]

swame thing you have. a locker. no clutches. i am sure its in a billion peices.

[FordWizKid]

Shit well, I was looking through your profile.... Is your motor really close to 500 HP ? if so I could kinda see why it detonated.. 8.8 out of a explorer is a good alternative and you can scoope em up pretty cheap.

[ZR1BLAZER]

last time it was at a dyno it was around 450 or so. but that was with other parts then whats on it now. i would have to guess a little over 400. but even then it ran good on the dyno and then like crap once it was installed. this is the worst hot rod i ever built? i think there is something or someone ^^^ trying to tell me to just leave it alone and cut my losses?

[tracker]

dont get discouraged my friend. i am having a hard time getting my blazer to run again and i felt the same way. thought about going carb just to get it out of the garage but that will take more time and money. so i just walk away from it for a while and get on it later.



if i were you i would put the known good stock rear under the truck and take your freshly built/blown rear to that professional builder and have him redo his work. should have a warranty on his work.

[ZR1BLAZER]

if it was the work? i bought the posi and gears and install kit. he just put it in so you know how that will go. he will blame it on the parts and they will blame it on the mechanic. the scary thing is. what if i put the stock rear in and it does the same thing? then i am out either way with 2 broke rears and no money to replace either?

[spacecadet]

I would suggest just slaping in the old stocker. It sounds like there was a problem with the new rear. Escpecially if it only had 0 miles on it.



I\'ve only learned the art of rebuilding rears recently. A friend that has helped \"show me the ropes\" told me to buy used gears for my race car. The reason was because the used gears were already heat treated from use. A new set would have to go through a seris of heat and cool before I could put a beatin\' on them. Or else it was possible they could break.

Well, I don\'t know how true that really is, But I can tell you that I ran the season with the old gears and they still work. Another friend had bought the gears new and had to replace 2 sets this past season. Coincindence??? I don\'t know.



Thats just my 2 cents.

Space.

[ZR1BLAZER]

i dont know what to do. i have other obsticals in way as well. like no shop access any more? i have to strip down a second blazer with no where to do it but in the rocks. i always help everyone else but for some strange reason i never get any in return. there are just a number of reasons why i should just stop now. but i am going to think on this one long and hard. im not going to just jump to a desision to fast. thanks for the support guys. oh by the way. the quick 30 sec smoke fest that i did have was bad ass i thought i was going to piss myself. if it was just for a split second it was a VERY GOOD feeling.

[redneckgames]

see! how could you just stop and give up this close? I know money is an issue, believe me I know. Why stop doing something you love to do?

[ZR1BLAZER]

some times we all get a little discouraged i guess? lack of time, help, and $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$

[redneckgames]

yeah tell me about it. I took my truck apart in april. Took alot longer to get it ready to paint, then got srewed by the guy going to paint it. Finally got the motor together and in, truck painted, even had it to where we could drive it on the road. It was about 80% done. I was so excitied. Now I find that the oil is full of metal and the cam has atleast one flat lobe.

I mean it all happens for a reason. Its hard to see now but there is a reason for it. I hadn\'t planned on putting near the amount of money into my truck then it took. Or is still taking. Dad had to pay alot more than I wanted him too. Thats just the way things go I reckon. Just hang in there. You almost have it.

[Scotty_S-15]

That is certainly discouraging, but hang in there. Give it a little time and you\'ll feel much better about it I\'m sure. But yeah, a major bummer.

[carkiller]

like the others said, must of been something wrong with the rear. im running a 7.5 rear with 4:10\'s, 28x11 slicks, no problems yet. over a hundred passes.

[ZR1BLAZER]

thats what i am starting to think. i am going to swap in the stock rear for now and see what happens. if it breaks i always have income tax time. and i will let it sit till then.

[Indiana]

I am using stock and I have not had a problem. I don\'t know what hp I am running, but it has held up for one season.

yah and i have seen your crazy 3 block long smoke fest too. so i am starting to think that the rear was wrong? that will be another fight i guess?

[Scotty_S-15]

Who knows what could be wrong until you peek inside. Did anyone ever put grease in it? http://www.s10v8.com/images/smilies/icon_razz.gif

......... I had a \"pro\" build my Mopar 8-3/4\" for my S-10 back in \'98. I bolted the rear in, went around the block for the first time, barely made it home. The rear was SLIPPING. Yes, slipping. WTF? And, a tiny bit of noise. So I\'m scratching my head, then realize I was driving home on the posi, I mean, what else could be slipping in a rear? So I theorzie that only one axle was engaged, and the posi was doing ALL the work, and I live on a pretty steep hill. So I pull it all apart, and find that they made one axle too short, just barely engaged, stripped it out just driving around the block. What shitheads. They made good for it all, but in the meanwhile I lost another 2 weeks.

........... Bottom line, lots of weird stuff might have happened, won\'t know until you pull the cover off.

[Indiana]

I went through two sets of the vette tires, and a pair of slicks. I burnt the vette tires so much that I had cords slapping the side of my truck leaving rubber marks.

[ZR1BLAZER]

heres another question. would pinion angle have anything to do with this happening? i have it dropped with steel blocks. 4\" but the pinion angle looks good. not perfect but not all out of wack. i have seen people drive with the pinion angle pointing at the street or at the bed and not have problems but just in shitty lowriders never a v8. mine is straight with a slight angle towards the top. very slight.

[Indiana]

It would have effect over time, but not that soon and not the rear gears. It would wear the u joints and the tail shaft more than anything.

[ZR1BLAZER]

thats what i was thinking but figured i would ask anyway. i should be able to do something with it in a couple of days. i will take some pics and let you guys tell me what you think.

[elv408]

There is no way to tell what happened in the rearend unless you open her up!



I have a 7.5 w/ stock 3:42\'s. One day my rearend started making a clumping noise. Removed the cover and found metal shavings and a broken cross shaft pin. I think what happened is the little 5/16\" pin that holds the cross pin in Sheared and the shavings were from that stuff grinding.

I washed down the case and replaced the spider gears and put her back on the road.



I think the rear busted from a combo of too many original miles and too many Hole shots with the V8.

[sorj]

Dayna,

it sounds like the so called professional had the carrier too tight. I have seen where some people set them up on the tight side oly to have them lock up after they heat up. In your case, you were in the power band of the engine \"getin - it - dun\" when she heated up. POW!! there she went.

[4x4blazersbc]

Did the person that builted the rear for you tell you how to brake it in? i have only rebuilt on rear end and i remeber having to drive it for a while not going over 55 mph. Before doing that i had to run it on the lift for 30 mins. and let it cool for an hour before driving the car.

just my 2 cents

[DROPPEDATBIRTH]

I agree with everyone else but I know how you feel I\'m on my third motor and spending money always sucks, when you have a toy thats what it is a toy and I know it\'s hard to say but you really can\'t expect a toy to be reliable. If you have another ride I would just park the blazer and forget about it for a few, then start on it, I was going to sell mine after the second motor but I let it sit for 3 months and started working on it again, and I\'m glad I did.
