Hi, 2010 warrior 112000 miles vibration through chassis that starts as a deep hum at about 68 mph to a full on vibration that makes the rear view mirror un useable, i bought the truck knowing avout this issue (its my bosses old pick up) and its been like it 18 months or so, its had a full set of brand new. tyres recently fitted and balanced and the wheels swapped from front to back to eliminate any issue with the wheels and tyres as the hum/vibe still comes up through the chassis and nothing through steering. It had a new gear box mounting n/s recently to try to combat problem but still same. Rear prop still has the original weights frim the factory firmly in place so should still be balanced. U/j appears good. Boss has had it seen by three different garages with nothing conclusive (although i suspect these garages were just told to have a quick look when they service it......

Any ideas greatfully received
