I have replaced the wheel, carrier and pinion bearings in the 68 3/4 ton chunk I put into my 1 ton rear (5.14 to 4.11).
I replaced these bearings because of a rumble coming from the rear. Changing the bearings cured the rumble but let me hear a terrible whinning from the rear. VERY annoying!
The ring gear and pinion gear are pitted and rough and I guess I will replace them both as the shop manual says the noise can come from rough or pitted gears.
Question: Can anyone advise where I can find a 4.10 ring and pinion set for a 68 chunk? Any of our sponsers?
How hard is it to change the gears relative to replacing pistons for example? Thanks
