My past experience with axle bearings is that they go way longer than 80K miles. The seals are 30 years old though and that might be what goes first. But, the axles don't get ruined if that happens. The oil in this axle has been changed too. I had new gears and a posi put in about 25K miles ago.
Again, maybe I'll give this more thought at the next brake job.
I don't put many miles on this car, but I do want it safe and reliable.
Btw, this is an original Choo Choo SS car and is fairly rare for a 1983 model. I put an LT1/4L60E in it back in 1998. The engine and transmission came out of a '96 Impala SS that was taken out of the car when it only had 100 miles on it. I've only put 25K miles on it since then. I did the rear gear change at the same time.
I thought you guys might like to see the car we're talking about. Pics always make a thread more interesting.
