My 78 S/A had 59K 12 years ago when I took it it the Corvette Barnes here in Syracuse for an alignment. The owner was a C3 team race guy from the 70. They suggested I do a front and rear end suspension rebuild and $60 install of a grease fitting in the rear bearing carrier of the rear trailing arms. I have 101600K on the Odemeter but I think it should be 122000K because the odometer reads 25% low.
when I have the yearly New York inspection I have them grease the front end and a small amount of grease in the rear bearing carrier.
These pictures are not the best, but they should give you an idea of where they are.
Grease fitting for the rear wheel bearing has been around for a long time, but experts like Gary Ramadei who routinely rebuilds trailing arms told me personally that its not a good idea:
Yes
