Hi all

F150 lariat, 4x4, 5.4l crew cab

Have a vibration while driving at speeds from 60 kmh +, get worse the faster you drive, feels like its coming from the rear of the truck
drive shaft was missing a wieght so had the drive shaft balanced, new u joints, pinion seal, and rear flange were also replaced
still have the vibration, not as bad, but still there
had the tires balanced, they were fine

any ideas?

Thx

Bill

should add the truck has 200k and the rear diff has the additive in there for the slipping.

Yeah...maybe need some shocks...

Suspension was serviced last month, both leaf springs were replaced with 3/4 ton springs, shocks were checked then and were ok
I'll get them. Checked again, but seems unlikely that that is the prob, just the way its vibrating, seems like its in the drive line
