Rear end questions

One_live95 · 09-03-2005, 07:31 PM

Well since i have had some other problems with my car, suspension related etc, i removed my struts to put on my c/c plates, and springs, struts are busted, and one is bent, i guess because of it being so low....???

I have yet to tear into the rear end, it will get 3.73's, and was supposed to get a new differential, but i don't know if that is gonna be in the budget. I have heard that you can buy two trac-lok rebuild kits and pack them in a manner that it is a lot tougher and much less likely to slip, so i am looking to some of the experts on here to help me distinguish between myth and fact, and maybe help me figure out what my options are.

Can a rebuilt facotry diff. withstand much power, traction, etc.? I was looking at the detroit truetrac differential, would i have just as much money in fixing my stocker "Well" as i would in buying aftermarket etc.... or what...

Someone please give me some options, and opinions, i am not as knowledgable about rear ends etc. as i would like to be, so i really am not sure which direction i should go in....

thanks

You can rebuild the factory trac loc and put in an extra clutch and disc and replace the "s" spring between the spider gears with one from an f series truck that had an 8.8. If possible try and find and explorer or ranger center section for an 8.8 that was 4x4 as they are 31spline units and you will need to get some 31 spline axles.

but with the extra clutch and disk , it will make it a lot stronger.....ex... grab better, no slippage etc. Wonder how much i could find the center section etc. for, i have seen the moser 31 spline in summit for around 250$...... little cheaper...

we use two FRPP rebuild kits when building the rearends. The f-series s spring is a pain in the ass but will work.

My car is still running the stock 28 spline setup, 3.73's, and the 'extra' clutch rebuild

so it will hold then right Lee? I am buying parts for the car..... bought a line lock, all the tune up stuff, and just trying to buy what i need to get it up and going, the 4.10's may actually have to stay in for a while.....dunno though. Will the stock S spring be ok or will it need replacing, i have seen the stronger one listed in the FRPP catalog how would that one be....???

's' spring will be fine. just get the diff rebuilt with the extra clutch

Mine was 28 spline with moser axles and c clip eliminators, rebuilt the traction lock with 2 packs of clutches, yes it is going to slip a bit becaus if it don'ts you will have a terrible noise in the rear end when turning. Mine saw launches of 5k on the nitrous when it was a manual car, then 2500rpm foot brake and stump it from the launch on nitrous, lasted almost 10yrs, until Spring brake shoot out last march in Orlando when I broke it, with a 325 shot!

Thats what I would do, just double pack the clutches. These 8.8's are stronger than what you think.
