process of elimination - vibration
My 2000 GC limited (4.7, quadradrive, 104k miles) has a vibration that occurs at 70-75 mph under load, either accelerating or going uphill with the cruise on. If I back off the throttle, it goes away. The vibration becomes less noticable above 75 mph. A check of front end components didnt reveal anything obvious being out of sorts. There is no clunking when shifting from P to R to D. I'm thinking of pulling the front DS to see of it may be the culprit. What do you think? By the way, being a newbie, love the forum!:p

Re: process of elimination - vibration
Vibration issues are many times not so easy to find. Removing the front DS is a good start (put a mark on the couplings, so that you will put it back in the same position as it was before, otherwise you could end up with even more vibration) . Maybe also balancing the wheels to rule out unbalance. Did this vibration suddenly start, or was any kind of maintenance done?
Regarding the DS, there are some balancing weights soldered on them, just check if they are not gone (they are quite small on my Jeep, so don't know if missing them would make a big difference)

Re: process of elimination - vibration
The onset of the vibration has been graduadual. I'll pull the ds & see if it disappears. I'll post my findings.
