rear end problems (long)
88 zuk that had a welded rear end with 5.13 r+p, they welded the spider gears in two slots on each side of the spider gear. About a month ago after a hard launch on pavement I heard a pop in the rear end over the next few days, usually when turning sharply.
Then no noise and the rear seemed to be an open differential, I could drive in tight circles and never get a tire chirp or shifting of the vehicle as it did when it was still welded.
So I knew I needed to change my oil due to weld chunks surely bieng in the oil. So I did [img]images/graemlins/confused.gif[/img], and immediately after changing out the oil it started popping as if it were a worn out locker, the tighter I turned the more it popped and grinded. (keep in mind this is my daily driver or it would have been parked by now).
It would do fine on the highway, but after 2-3 days, noises more frequent, and now ever the slightest turn would make it pop and grind. It got to the point yesterday that 1,2 and 3rd gear would make it pop and sometimes while in 4th and 5th, it feels like a slipping clutch, but the noise and jolt when it would catch clearly pointed to the rearend.
So today I pop the axles out, pull the 3rd member out (my first time yanking this piece out), and start snooping around.
all of the teeth on the ?ring gear? are very shiny as if contact is beig made everywhere on the teeth except for the very inner and outer edges by the bottom corner of each tooth. AS i spin the pinion there is 1 spot that I can barely get it to spin past, I have to grab the gear with one hand and the pinion with the other to get it to spin??
When the ring is moving freely there is a very slight amount of play while I move the pinion back and forth as the teeth engage (a very small amount of play).
The noise I experienced sounded as if it were going to bust an axle shaft, what the help is going on with this thing?
