1995 wheel axle nut torque spec

Hi all

Can anyone from FSM tell me torque spec for spindle nut?

36mm hex nut rear axle, taken a look around somewhere says 164, some other 174 or even 200 lb /ft

Thanks

I've never seen the C4 FSM updated or a TSB related that increased the spec from 164 lbft. I do believe that there was a TSB for later generation (C6) but I've certainly not looked.

I haven't looked either for a C4 spec change for many years.

From what I understand there are a number of s10s that use the same bearing on the front.

The torque spec for the S10 is 181 ft/lbs
The torque spec for the C4 is 164 ft/lbs

I've seen higher numbers for the bearing nut when used on "steering axles" and that bearing was used on many FWD cars. None of the applications I believe are newer than '90 and even some/most of the after-market mention the 164 number, others mention the number for the specific application.

Assembly is a little different on the applications where it's installed on a steering axle.

I didn't miss anything, the FWD "steering axles" I'm quite sure didn't have a thrust washer like the C4 rear axle applications have.

Actually I believe you can only find the interchange of the hub/bearing in after-market applications where I believe the vendor assumes the liability for the hub/bearing to be an acceptable replacement.

That can certainly and is debated often. It's an "unknown" and a gamble for sure. The tooling for even the highest quality production suppliers is likely worn out and I doubt any of them continue to provide product that's within OE specs or for that matter their own specs of just a few years ago.

I believe that all of them likely just provide a product that can be "priced" to where it's thought to be competitive. There are likely exceptions but will the majority pay? Probably not.

Your location certainly doesn't give you much of a shopping choice, I'm sure it's a difficult decision.

The largest supplier of hub bearings to the OE in the US NTN/BCA doesn't even offer the bearing discussed here. Likely the tooling wore out and it's easier to just "quit" and focus on long run OE product.

Well as your so sure that going over 164 ft/lbs is harmful IF I remember to I will tell you how many thousands of miles my replacement bearing lasted at 190 when it fails.

From what I have seen on this and other forums, Timken and SKF are the 2 most recommended bearings to use on our cars..Both are around $150.00, but you can't go wrong with either one..

Just replaced my rear drivers side today. I torqued it to 150lbs then turned far enough to get the cotter pin in. I figured that probably put it close to where it needed to be.

I definetely torque them at 164 ft/lb

I've mailed at corvette central to ask them this info, they said the Torque for my year (1995) according to FSM is 164 ft/lb

Replaced rear bearing with NATIONAL 513020, very good part, new teflon washers, greased well inside spindles washer ecc...

This way fixed very well rear clicking sound, thought culprit was grease lack inside
