Last night my back right axle started making a nasty clicking noise. It doesn't have any axial play or runout, both axles slide side to side in the cups. Which I assume is normal since they're both DOJ cups. Anyway, I gave the right axle a good shake in the cups and now it doens't make any more nasty noise, so I dunno what's up with that... If that's a sign of impending doom.
No torn boots, no leaking boots, nothing like that.
