Finally changing to 4:10 gears......any other tips, tricks or recommedations?

Okay, I am finally getting to my differential and gears and looking for any thoughts of what else to do while I am under there. I am going to use the factory service manual procedures and drop the entire unit in my garage myself.

So far, I have:

- the complete kit with bearings, ring and pinion etc. that I will have a local shop r/r with stock unit

- speedo correction gears from Marc Haibeck

- C Beam plates

I will buy:

poly bushings and synthetic gear oil/w posi additive

Is there any thing I should look for other than the wear of tear of related items while I am under there or any recommendations from the experienced folks. This is my first time touching the differential, but I think I have all the tools needed for this job. My clutch is stock but fairly new so I'm not going to touch it yet. The 90 Z has 53K on it and the clutch only about 5K.

Thanks in advance and Happy New Year!

Be sure your bearing kit also includes the side yoke bearings and seals. A lot of kits don't. While doing mine I converted the carrier caps from 1/2" bolts over to 1/2' ARP studs. Here are the ARP Part Numbers:
4 x Stud - AR4.060-LB
4 x Hex Nut - 200-8607
4 x Washer - 200-8514
To order you have to call ARP Order Desk & Technical Support: 800.826.3045



You might also have a drain plug installed like in this pic while you have the case at the shop. Makes it a lot easier to service next time.



In case you are interested here is a pic showing the stock 3.45 ring and pinion next to a Viper 4.10 set and a Yukon 4.10 set.
The Viper gear set is quite a bit more substantial.

Thanks a lot, I really appreciate the input and recommendations. I'll definitely look into these; I might as well do it right the first time.

I really appreciate the information and pictures; truly awesome and just like David said about getting your advice. I sent you an email.

Jagdpanzer,

Thanks again and I guess you might have heard from ZZZZZR1 (David) that I have Yukon gears and this kit:

I guess I might have to consider getting some Viper gears?

I do have the drain plug kit from Corvette Clinic too; at the time I thought I was just going to install it and not change the gears.

Phil,

I really appreciate all your help and thought since I had a "Master Overhaul Kit" I was good to go. Thanks for the referral for the Viper gears too. Thanks for helping me do this right.

Big Mahalo and Aloha,

Craig,

You need help in dropping your rear end, let me know. Dropped mine a few times already.
