I'm hoping it is the spring mounts......did you 'freak out' when the forum was down and do a few high speed "Baja runs" in the local gravel pit to ease your frustrations? Come on, tell the truth, Richard's feelings won't be hurt!
I would support Smitty's comments and echo that they are all JUNK, however some are less junky than others. Expensive junk. SHOW ME THE MONEY in a damned 50K non diesel pickup!!!!!!!!!!!!!!!!!! ....or give me a link to the 'personal lubrication center' for the diesel variety.....How can a gasoline pickup get 8 mpg and a 70K lb 550 hp TT or wheeler get 5 carting a full load? Any qualified mechanic will tell you horror stories about all of them. How are those Mercer electronics doing? Mechanically excellent, electronically JUNK! Any friends running the vans (50K blue tech) Sprinter my a$$, they are like a damned helicopter.....i hr on the road, 10 in the shop.
Smitty told be back in the day, he had wife that caused him similar incidents to what you identify.....perhaps Dr Phil has some advice......just a thought.
