Never said if 4wd but if so have the lower ball joints been done, the tires balanced, steering components good, hubs not bad, and then for performance was a complete turnup done with cap/rotor/plugs/wires/air and fuel filter? Any SES light so codes present? Coolant not leaking either internally or externally? Brakes done and rears not dragging? Lots of things need replacing/work by 100k - sorry.

My 2000 GMC Jimmy 2WD with nearly 200,000 miles on it vibrates, becomes fairly noticable around 25-30 mph, is very noticable between 45 and 70 mph, then sort of tapers off above 70. When I let off the gas, the vibration disappears completely after 1-2 seconds, but returns the instant I press the accelerator. Recently did all front ball joints, idler arm replaced, tie-rods check out ok, still need to replace the center link.
The shop told me that it was uneven wear of the front right tire (left was replaced recently and is nearly new), but I failed to tell them about the vibration disappearing when taking my foot off the gas.
Anyone have a clue? I'm thinkin U-joints to start.

I took my Jimmy for it's 60K service. The car ran perfect. Now after the service I've had to replace two fuel sending units, radiator, intake manifold gasket, shock, battery cables, and battery. I just paid it off and spent $2K on repairs. Now it vibrates whereas before I couldn't even tell if the car was started because it ran so smoothly. What do you think this is? I'm so distressed.

U-joints would be good and how about the front hubs. That cenetr linkis often the source of play on 2wds.

Take it back and let them find it. Could be many small things they did not get right. Now if its only a rattling at idle that commonly is the PCV having teh throttle cable contacting it as the rear manifold plastic holddown always breaks when you do the intake - secure the cable with a plastic zip away form the PCV - if thats the noise.

I didn't have the shop do the actual work that needed doing. I only had them diagnose the problems. Doing the repairs myself has never been a problem, it's figuring out where to start that I have issue with.
I was thinking the hub too, but I replaced the passenger side hub about a year ago and there was a distinct shimmy in the steering wheel that went along w/ the bad hub, so I ruled that out (for now).

Hubs usually have a grating noise and some play so jack it up under the A-arm and check it out.
