Thump and bump
Have a problem that I have researched on FTE But to no avail..
When accelerating from a stop a thump is herd and "Felt" towards the rear of the truck.
95 F-150 4X4 Rancho Lift 97,000 miles.
I replaced the trans mount and the engine mounts and the thump still is there.
Took it to a Four wheel shop today and the Tech had no idea what was causing it.
He recommended a trans shop. I have read quite a few Fixes but nothing definative. All bushings, mounts, and springs are intact. Trans has 30,000 on it and no leaks.
Sugestions?

Possiably, Not sure.
The tech was stumped so, Most likley off to the trans shop as recommended.
Just want to avoid throwing money at the problem.
Thanks for the hint though.
So far i have a list for the next tech to look at.
Slip yoke
Trans modulator
vac lines
U-joints
Tranny not dropping into 1st gear when stopping.
Trans tailshaft bushings loose.
Carrier bearing on Drv. shaft
Thanks for the Idea.
When i find out what is causings I'll be sure to post it to help other users save a few bucks and aggravation.
Cheers,
J.
