Got the shakes
I've got a problem with a vibration that comes on at about 80-100 km/h (50-65 mph). I've got a 4.0L 4x4 auto trans. I've had recent work done on the front end (new ball joints) and the alignment was done at that time (it was when I bought the truck, the shop I bought it from did all these to pass safety inspection). The tranny was also flushed at this time.
Things I've tried:
1) had the wheels balanced multiple times AND put a different set of rims and tires on and drove around. still got the shakes at around the same speed
2) driveshaft was rebalance with new U-joints on both ends. Again, this did nothing (I'm kinda cheesed about this one as it cost about $300 but this was the opinion of the guys doing the work that are really reputable. I did agree that the U-joints were somewhat off but the rebalancing probably didn't need to be done)
These 2 things, as I was told, account for about 95% of the vibration troubles.
Weird thing is that the severity seems to be inconsistent - sometimes it's really bad and other times not too terrible. It also does not feel as bad if the truck is cold. It does not really feel like it comes through the steering wheel but more through the seat. Maybe just my imagination.
There have been many suggestions (tranny, rear end, etc. but I hope it is something a WHOLE lot less expensive, etc.) was wondering if anyone else has had this problem and what the suggestions are to fix it.
