QuestionMy father had a 2001 Jimmy with a shake that developed within the first 130-140 miles of the vehicle's life. This was not resolved, and the front-end was inspected, tightened, and retightened. No problems were found. The vibration happened around 55-65 and shook the whole vehicle. This car was traded in after the lease.
I personally own a 2000 GMC Jimmy Diamond and was in a front-end collision where a lady backed into me going appx 15-20 mph. I was in reverse, but completely stopped when she hit me (was waiting for traffic to clear for 45-60 seconds - so there was no way I was moving). My car was at an angle of about 11 o'clock with the wheels completely turned to the left, and she was traveling straight at 12 o'clock. She hit me hard enough to dislodge both front headlights, and pushed the factory Grill Guard so hard into the bumper that it recessed the bumper 1" (both mounted on different parts of the frame). I've had all 4 tires replaced (she broke the belt(s) on the front left and rear right tires because of the counter-clockwise torque applied to the vehicle), and had to also replace the front left wheel bearing as a result of the accident.
The problem is that before the accident there was no vibration, but now there is an identical vibration at 55-65 that my father experienced in his Jimmy. The dealer says that both axels are not bent, and that the rear break drums have been rebalanced. They even put 4 new tires/rims on it from a non-vibrating jimmy and the vibration still persists. It only occurs betweeen 55 and 68, and seems to resolve above 68. Also, sometimes it goes away if i get into the left lane of the highway (i'm thinking because of the pitch of the road). I feel the vibration in the entire vehicle, and I have not noticed the steering wheel vibrating back and forth (thou I can feel it in the steering wheel, but I guess this indicates it is something in the back maybe? From my understanding, if this was a front-end problem the steering wheel would be noticably shaking?) The SUV has been in the shop over 3 weeks now and nobody can figure out where the shake is coming from. Any help in pointing them in the right direction would be INCREDIBLY helpful!!
AnswerHi,Dan
Is the Jimmy a 4 wheel drive?have both driveshafts checked,also check the driveshaft to yoke angles,or driveshaft angle to see if its in specs,ive just finished a 05 Cadillac Escalade with the same problem,i spent 5 days on this vibration and found the driveshaft angles to great causing this problem,the rear trans mount was shifted to far left causing the driveshaft angle to be excessive,this{what we call}detuned the driveshaft causing the vibration,have those or the rear driveshaft checked.
