At 130K, theyre not far from going. U-joints too. So start listening for weird noises from the rear.

My first went at about 131, the pass rear. In a couple of paychecks, provided it doesnt break before then, I'll be doing the drivers' rear and U-joint.

thanks for the input .believe me i know all about ujoints i did replace those at 100k. :chevy

Don't have answer to your question, but I wonder about the life of the lubricant on wheel bearings on cars that are driven only limited miles per year.

Can't remember the last time I heard anyone talking about cleaning & repacking wheel bearings.

Just thinking on my car(96) it is now going on 8years with original lubricant & brakes are in good shape since almost 100% highway. So time not mileage might govern lub life.

How often should we clean & repack front wheel bearings???? Every 5 years or mileage or what???

All 4 hub/bearing assemblies on C4s are sealed units. No maintenance and you have to replace them when they go bad.

Yep, their sealed. .....and stand by for the price of new ones. :D

I just did my rears at 96K.
Buy them at PepBoys about $150.00, make sure they are made by Chicago Rawhide, that who makes the AC Delco ones :cheers:

The reason you dont hear it is because we cant do that, ours are a sealed unit. I dont recall ever hearing someone was able to clean and repack a stock corvette C4 bearing.

I replaced the fronts on the 86 this past weekend at 135,000. The rears went first at about 128,000. I know some guys have had to replace them as early as 75 - 80K on their 92s and later.

I have over 158,000 miles and I have not had any bearing problems ( :smash: on wood). U-Joints went out around 90,000 miles.

Yep, I've never heard of anyone repacking wheel bearings on a C4, now I know why!!!!

I did clean & repack non-vette wheel bearings way back as a teenager. oops my age may be showing....

I think many cars these days have sealed wheel bearing assemblies. More expensive, but faster repairs. Time is money, so I suppose it evens out.

I have 320,000+ and have never replaced the wheel bearings. U-joints in the drive shaft and half shafts 3 times, lower ***** joint once, shocks once no other suspension components. Last two sets of tires I got 86,000 on Yokahama A540's and 52,000 on a set of Falken 512 Zeix. Just put on Dunlop 5000's and 4 wheel alignment everything looked good.
