Last season I snapped the right side output shaft (smaller shaft), and thanks to this great write-up (http://www.c5frc.com/DIY/Hardened_Ou...haft/index.htm) I was able to take my diff. apart to inspect it. I ordered all the heavy duty parts from RPM Transmissions (HD clutch packs/springs, HD shafts, Seals/O-Rings) Great customer service by the way, Thanks a bunch Todd! But they didn't send me a RPM T-Shirt, I guess they only keep them for the A4 conversion guys. jk

I'm about to put everything back together for the first time, and before bolting everything back on, I would like some helpful advice from the pros. Below is my list of questions:

1) I'd like to clean off the gunk/oil covered on the housing/casing, what cleaning product would you recommend for this job?

2) RPM and DTE seem to paint their diffs, which paint product(s) can I safely use? (high temp paint, primer)

3) Which 'Anaerobic Sealant' product(s) do you recommend? Also, where exactly should I apply it?

4) When putting everything back inside the housing/casing, is there anything specific I need to pay close attention too? Is everything I need to know mentioned in the write-up above? (torque specs, alignment, tolerances, pattern to install clutch packs/springs)

5) I'm switching gear oil to AMSOIL Synthetic extreme pressure 75w-140 (svo), is this a good idea? or should I stick with Synthetic extreme pressure 75w-90 (svg) instead? Also, do I need to purchase a bottle of AMSOIL slip lock differential additive (ada)? If so, how much is required?

6) Once everything is back together, what's the proper break-in procedure?

I apologies for all the questions, but I want to make sure I do this right the first time. Any helpful advice would be greatly appreciated. Thx!

Just a bit of feedback would help. You don't have to answer all my questions.

 

Here is your answer to the sealer question. Very good post!!!

Not sure if RPM uses the same/similar clutch pack as DTE, but their fluid requirements are very specific. I know that they use the Redline 75W-140, but I also think they double the limited slip additive. You might want to check with them on this.

 

I know Todd@RPM said they use Valvoline SynPower Gear Oil (75w-90) + GM limited slip additive. I'd rather stick with AMSOIL products. Since nobody can confirm that 75w-140 is better, I'll go 75w-90 to play it safe.

Thanks for the feedback!
