10 Bolt on the way out?

[lozanoa11]

Yea hold the u-joint and try to move the drive shaft. It will be evident if it is it.

Could be a bad pinion bearing, my 94 made a horrid noise when decelerating and it was the pinion bearing. It was like a 200 dollar fix not bad..

I FINALLY had a chance to check this this weekend, ring & pinion gears are shot. I can turn the drivshaft ~ 1/8th of a turn before the pinion engages the ring. Thats how much slop there is, when it gets put in gear it clunks and again when it shifts.

Guess im out for a set of gears? Should last me through next year right? If I can spend 200 and make it work for another year, ill be happy with that. I dont have the cash for a 12 bolt.

These look right?

If you gotta buy some gears step it up a little and get a 3:73!

Not gonna happen, I love my mileage, I put anywhere from 25 to 75 highway miles on my car a day, plus what I drive in the city.

I was also looking at some threads on ls1tech, apparently there is a fair amount of slop in the center section, just a 10 bolt thing.

Hears the deal though, I went out to the back barn and dug my old open dif 3.08 10 bolt out. Started messing with it and it has ZERO slop from the input/pinion shaft. If I turn the shaft a millimeter the axles turn.

So what gives? And where is everyone this morning?

Slop in the axle really has nothing to do with your ring and pinion. Most of the time its all in the Posi/center section itself.

[sman]

So your saying my problem is the center section?

[c0ncEpT]

If there was enough slop in the ring and pinion itself for you to turn the driveshaft 1/4 turn before they touched in either direction the 1st time you launched the car or got a good 2-1 downshift at WOT it would shatter everything inside of their.

You said you can turn it only an 1/8th of a turn? That seems 100% normal to me. I would be more worried if it didn't have any play at all. I would think it was binding up.

There is no slop in the original 89xxx mile rear end out of my car. Not saying its right either, just trying to figure this out.

This rear did come from an m6 car, only had 30k on it when I bought it, but I dont remember it being like this.

Isnt the part that normally goes bad in these the ring and pinion though? I understand what your saying about that much slop and it not exploding all over the place, I dont understand it either. But I dont remember all these clunks and noises I hear before I went to the track though.

Have you even pulled the cover and inspected it?

[sman]

As its my only mode of transportation until this weekend, no. Thats the plan for saturday morning. As of friday the insurance turns back on on my intrepid and that will take DD status. At that point I will probably turn the insurance off on the camaro as I just dont think whatevers wrong with it is going to be quick or easy.

[c0ncEpT]

To tell you the truth I doubt something is wrong with it to were its going to break. I think its all in your head. We have guys on this site that have been VERY hard on ten bolts on the street and at the track on stickys and haven't had a problem. I would say that 85% of the 10 bolts you hear about breaking are stick cars and the other 15% are very high HP auto cars.

I just got done with engine pull and replace. As I remember the rear when the drive shaft was off I had emergency brake on an at best the was very slight play. If you want to break it to a measurement I would say 1/16 or 1/32 of a turn, very little but some play.
When you check it again put on e brake it locks the axles, so you will feel the play in the center section and ring and pinion. Just a suggesion.

When I did it the car was on a 4 post lift, trans was in neutral and the parking brake was set as tight as I could get it.
