On my way into work today I started getting a slight clunking feeling as I was coming to a stop, well needless to say when I started to go again when the light turned green it had a slight clunk as well when taking off. After about 10 feet slight clunking turned into hard clunking and I was pulling over and towing it home. My car is a 98 Z28 with the stock 10 bolt and 3:73 gears which have been in for a while...to be honest now is not the time for a 12 bolt or a 9 inch for me. I have a rearend out of a 1988 IROC camaro and was wondering if I could use the entire rearend and just switch over my braking system. If not could I use any of the internals to repair mine? I have not taken mine apart yet so I can not tell you exactly what is wrong. The car will still move but it makes a lot of noise...Any advise would be greatly appreciated.

 

Well that is what mine sounded like when i launched off the line and snapped the axle .

 

You should be able to use the internals, but don't use the whole thing as it is wider then a 4th gen axle. So I guess you couldn't use the axle shafts, but you could use the gears and diff.

 

it sound like the gears mine did the same thing u can us the internals out of the 3rd gen rear but the forth gen rear is 2" longer on each side

 

It looks like i broke a few teeth on the pinion and the ring gear...looks like I will be going back to the old set of 3:23's.

 

Check the yoke of hte driveshaft. If your driveshaft yoke broke, it sounds very harsh like your riding on rims, no tires.

 

i agree with juicedZ...u prob broke ur ring and pinion teeth...ive had that happen...richmond gears are junk so if u had them and u plan on buyin new ones id go with gm genuine gears ...thats wut i run now and no problems thus far

 

This will be the 3rd time I'm posting this, but look into the last 2 issues of High Performance Pontiac. 2 articles on building your 10bolt to handle 425 rwhp for under $600, if you want to save money and buy time.
