Well I bought this diff knowing that the clutches may or may not go out. Long story short the guy used the wrong fluid. Well after a year of some abuse the rear goes peg on me more than posi. So I ordered the service kit.

So is this gonna be a real PITA??? Are there any tricks I should know about??

Auburn uses cones instead of clutch discs. When the cones wear down you genrally have to toss them. I read a post on a Pontiac GTO board about turning down the side gears in a lathe and shimming it up to gain a new wear surface, but I have never tried it. I prefer an Eaton or a Detroit Locker gear drive.

seems to be the norm. a while back i sold my new Auburn gear for a Detroit locker and then sold that for a spool but thats another story. whats a "service kit" ? you may be better off picking up a used unit. then again, rebuilding might not be as bad as it seems. keep us posted. im curious how one would install a "service kit". sorry im not much help but if you have the parts to fix it..............

If you have a manual transmission do not use a locker it is a pain in the ass when you slow down and turn at the same time.

If a new diff is the solution, may I reccommend a TrueTrac by Detriot (Eaton). After much debate and research, I put one in mine and love it. Looks like this: http://www.eaton.com/EatonCom/ProductsServices/PerformanceProducts/Products/Differentials/DetroitTruetrac/index.htm?ssSourceNodeId=5334&ssSourceSiteId=EatonCom

Yea a locker would have already been in the car if I didnt want to use the car for more than just straight line as wagon train knows Cool

My car is all wrong, the brakes are too big, wheels are too big, suspension is all wrong, its a stick but the driver is the biggest issue Laughing

That will not fix the problem. You can look at any forum and see the cone/reverse cone is terrible going around corners.( you still have to exit the drag strip 180*?) Just someting to think adout. Very Happy
Snap/ Crackle/ POP! Shocked Very Happy Again you are better off running a spool if that stuff is going on!

if thats all thats in the service kit then youre wasting your time. if i were you i think i would follow beersngars advise and get a True-Trac. i put a spool in mine but it can be a bit tricky driving on the street.

Screw a locker or spool, I'd consider it if I didnt like driving the car around corners, but if you guys really think I should get it start a fund for me... k thanks

As I'm often wrong take this with a grain of salt. I believe I read that the cone-clutch arrangement cannot be rebuilt. The fix is a return-replace program that Auburn operates. I've seen it stated in their ads. For turning corners the True-Trac is the hot ticket. Smooth all gear design means no clutches to wearout or grab and stronger overall.

I usually just stick with the stock posi and a little GM additive. If the clutches are worn out I usually dont try to rebuild them, I get a whole new posi carrier.

Actually they are pretty easy with a locker Smile. I have a Powertrax and I wouldn't recommend it for a daily driver either - stick with a limited slip of your choice. I had a Auburn Pro-series for a while and it started acting up, but their return / replace program only applied to a certain age unit - mine was too old - not many miles though. It did the screwiest thing before I sold it though. It worked fine in the street, but at the track it wouldn't pick up both tires, always the passenger, never the driver. Tried several methods, hitting the throttle hard, easing into it, etc. - same result. However if you put the car in reverse and barely blipped the throttle - not hard at all - and then started the burnout, it would pick up both tires every time. I thought it was a fluke, but I probably did it 50 times at the track and it worked every time. I never could figure out how it could be loading the cones different with that little blip. It got aggravating, so I sold it. Clay

You guys are right about the cones and they dont come in the service kit... So that order was canceled Laughing


The detroit true trac would be sweet, but its just not in the budget. The diff is 440 alone and than I have to pay to have it all setup unless I do it all myself and locate a bearing press and puller and make some dummy bearings. I'm gonna call auburn, but I'll still have to get everything setup again if I send the diff back...
