Lurch/jerk/vibrations
Folks, I'm looking at something going on with my power train, I think. So for a while, I've had a vibration noise at 30, a full on car shake at 60 (only at 60, decreases before/after at higher/lower speeds), and an a vibration effect at 75. I think its towards the back because the Rear Defrost lines are 'blurred' with the windshield from vibration (shake your hand back and forth in front of your face). U joints were replaced about 11k ago, but they were Duralast (in a bind, had to get something). Can't say if this problem was occurring before or after, because the front end was so worn out the car always shook a bit on the highway.
Something that might be related, if I'm driving and I take my foot off the gas too quick the car bucks like there is a delay in the driveshaft. This especially sucks with cruise control, as you set it, and you adjust, it stops accelerating and then rapidly starts again, causing a nice buck.
Driveshaft? Rear? Tranny?
4x4 manual, 3vze like in the sig

Thats the weekend plan!
what would I look for on tranny problems? I'm gonna drop the driveshaft and see if the sloppy feeling persists with just the front wheels

Check for excessive play at flanges. Any binding when turning shaft. T-case is gonna limit checking tranny. not much more I can think of at moment with out cracking things open. Can change oil, watch for any debris in oil or magnetic drain plug. Well excessive debris. Both tranny and t-case.

ooooh... so time to dig into some basics. Yes, gear oil, for tranny do not replace it with any other oils that are NOT "yellow metal safe" I only know of three and couldn't find any at local autozoe or advance. Easiest to use same in tcase but not necessarily unless forward shift but don't think you have one. Think the FAQs link at top of model section should have some basic maintenance.

I would put the rear axle on jack stands and see if you can find any issues by running thru the gears. It may at least remove the front end out of the equation. A good front end shop should be able to tell you if your steering has any problems.

Going to take it to a tire shop tomorrow and get them to fix the nail in the tire, plus have them rotated, aligned, and balanced.
