I put a 3" tough country lift on my 2011 reg cab 4x4
after i noticed that it made my rear drive shaft vibrate
the drive shaft on the reg. cab is very short and unlike the 4 doors and ex. cabs, it has no carrier barring. I had a new drive shaft fabricated w/ a cv. it helped but didnt eliminate the problem. anyone else have this problem? any suggestions?
also considering a steeper shim- already have a 2.5 degree
