Rear axle repair??

[just a 6]

Well i just found out why my 60' was so bad last summer A couple of weeks ago my front driveshaft U-joints went bad so i removed my front prop-shaft making it a RWD truck. Then i discovered that my limited slip in the rear only works sometimes. If i just get on it a little the left rear tire will spinn like crazy, but if i get on it really hard i get both tires to spinn. So last summer at the track, no wonder i got wheel spinn and 2.07' 60 times. Considering one rear and one front was the only tires that grab the track.

here is my question, is there any way to clean or adjust the rear slip, or is it just worn out? Anybody had any experience with rear slips on our trucks?

Thanks.

Not so quick. I took off my propshaft too when I finished off the factory tires and my truck's stock GM Gov-Lock rear end also worked like ass. I'd say it spun both tires about 40% of the time and just one, 60% of the time. It depended upon how I applied the throttle.

But nonetheless I cut a 1.68 60' on the stock chip just a few months later. I usually 60' in the 1.7's. I dont think our trucks spin enough off the line to really cause one of the rear tires to break open (at least not at my power level or below). If yours was spinning massively then perhaps your transfer case has problems or else this is all a big coincidence and your rear end really is bad.

FWIW just before I finished my bald factory tires, I was at the track (probably a bad idea given the tire condition) and I spun the left front tire bad enough off the line to generate burnout-rubber on the wheelwell and produced 1.8-1.9 60's depending on the amount of spin. But it definitely wasnt "massive" spin , nor 2.0 60's.

Has your front diff, rear diff, and transfer case fluids been serviced regularly?

Yes they been service regulary after i bought the truck 1.5 years ago, my viscous coupling is locked up in the transfercase. So there is no slipping in the t-case. My tires was and are bad. At the track last summer i could feel my front tires spinning (truck going sideways at take off) The truck was stock except for a Pitbull chip and left line at 7-8psi of boost.

That sounds like a lot of boost off the line. When my tires were bad I couldn't leave with more than 1-2 PSI tops before they would spin enough to affect 60' times.

With new tires I dont launch harder than 4.5-5 PSI for the same reason. If the track is cold/slippery like my last (and best) trip to the track, I can only launch with 2-3 PSI and it spins a fair amount and I get 1.8 60's.
