2008 LMM CC 2wd - U Joints - Hard shaking with trailer above 60 mph
Trying to decide if this is a driveline shake I'm experiencing.
Center Support Bearing - Dmax Store
New Energy Suspension Cab Mounts
Added shims to support bearing
Truck does not seem to vibrate unloaded. Truck is stock motor/transmission. 197,000 miles.
If I have a trailer, it shakes bad enough I can't stand to drive about 60mph. Unloaded or loaded. I can see the bed of the truck moving/shimmying in the mirror
Leaning toward U joints, I have a 2-piece shaft with the carrier in the middle.
What U-joints do I need? Seems like the Rear end cap is 31mm and the cap on the center u-joint is 36~mm. Seems like all the joints on merchant or Dmax Store are 1.4"/36mm
Thanks in advance.
