I removed and disassembled the passenger-side half-axle, both joints. I'll refer to the joints as inner (transmission side) and outer (wheel side).
First off, the bolts were a mess of lengths and threads. On top of that, the inner joint bolts were definitely not to torque - they came off way too easily.
Second, the holes in the cage for the inner joint were an extremely tight fit for the balls, I was barely able to work them out. On the outer joint, the balls easily dropped through the holes. For comparison, when I did the driver's side outer a month ago, the balls passed through that cage easily.
I thought both joints should be identical, but they clearly aren't quite.
Off to the races! On the inner joint, there was a single mid-sized pit on inside race, and a small pit on the outside race. Not super-bad, but not perfect either.
The outer joint was a real mess. The inside race had significant pitting on 5 of the 6 surfaces. The outside race scarring on several surfaces as well.
And, to top it all off, the outer joint (which had all the race scarring) was significantly discolored.
Two pics of outer joint. Note the dark discoloration all around the joint.
A pic of the inner joint for comparison. No dark wavy lines here.
Oh, and there were metal shavings all over my cleaning rag for the outer joint
Interestingly, all the balls seemed in good shape from both joints.
I presume this means I will need to replace the badly scarred joint entirely, and possibly the other joint as well. Dare I even keep the boot from the outer joint? I fear it will have nasty metal bits in it that I won't really be able to clean out.
Thanks for looking at all the pics and helping out!
