Shakes or Wobbles problem
1998 Chevy Blazer 6 cyl Four Wheel Drive Automatic 133000 miles

I brought it to the shop, two days in a row, first it was the CV shaft, now it's the rear end, I changed the rear seal, and put fluid back into it, but now I'm getting a shaking/wobbling. Is it my rear end, or a universal joint?

Which seal? Pinion?

What fluid did you add?

First thing I would check is to make sure everything is tight that was removed.

The u joint can be checked by grabbing the yoke in one hand and the driveshaft in the other. By twisting back and forth you can feel any play.

I changed the pinion seal in the rear, and the front pinion seal needs to be changed as well. The mechanic I took it to, said there was no other problems, but obviously with shaking there is more problems. It only shakes when I push the gas if that helps any. Only started shaking after I changed the seal and put fluid in.

What fluid was added?

What was the response when you took it back?
Ask him to recheck his work.

This problem sounds like it is in the drivetrain since the symptom is under load.
