Almost exactly a year back I replaced the bearings in right rear wheel, but a couple of days ago I noticed some play in that wheel. I thought more play than there should be (i.e. none to a teensy amount). So I pulled the bearing housing and this time taking the driveshaft and CV joints with it. That meant CV joint to transaxle connection detached. I had a spare assembly, all greased up and ready to go, was from my old ’82 westy and still ok.
Got it installed ok, never really a fun job. Then I had a look at the one year old rebuild. I had the notion that maybe the bearings might be loose in the bearing housings, but no, they had to be driven out with some effort. The outer bearing looked fine, but the inboard bearing looks discoloured.
And it feels slightly rough when spun. So what’s the story? Did I not lube it enough during install? This picture from then looks like I did not put much grease into the bearing, but what you see is the stuff I had smooshed into the bearing, more lube was put on after the bearing was in place.
Maybe I did screw up, wouldn’t be the first time.
Update: looking at the bearing again, I’m not so sure it overheated. It looks more like corrosion on the outside of the outer race. Still puzzling.
Addendum: I cleaned up the CV joints on the axle I removed and one joint is ok, the other is on its way out. I have to admit that I had not serviced the rear CVs since I bought this van a couple of years ago, it really should have been done. The grease was a bit dry on both joints, and one showed signs of impending failure (Ed. jeez, that sounds a bit over dramatic).
Outer race removed.
Expected and acceptable wear.
One of these balls is not like the other ones.
Inner race, would this erosion spread?
You kinda wonder if tri-annual repacking of CV joints is the way to go, or just replace them every seven years or so. It is a bit of a chore getting the axles off, and more of a chore cleaning and repacking. CV joints are about 90 bucks a piece here, I don’t know what is the best strategy.
