medium frequency vibration felt thru the steering column and drivers seat that is very fatiguing, between 60 khm and 120khm.

 

Get your tires looked for balancing, and get your alignment checked.

 

check driveshaft as well. Had a failing u joint that took a long tome to find as the vibration was very hard to pinpoint.

 

Thank you for your reply. I have already had the alignment checked, trims trued, tires balanced - even had a complete different set of rims and rubber installed - but no difference in the vibration
.

 

Thank you for your reply. Just had the drive shafts removed and u-joints checked, the diffs fluid replaced and vacuum tested, the tranmission fluids replaced.
No difference in the vibration.

 

How old are the tires?? I once had a issue with a set of out of round brand new tires. they balanced just fine, but were manufactured out of round. It took trying three complete sets (12 tires) to get one set that were ok.

Just a thought.....
