Hi folks,
I had a driveline vibration in my 1989 Toyota 1/2 ton, reg cab, reg box, 4 speed manual 22R.
It has 180,000 miles on it. I removed the driveshaft and replaced the u-joints, 1 was pretty sticky.
I'm getting a difference vibration now and it's kind of stumping me
around 40 mph in 3rd gear (turning just under 2000 rpm) I get a shake in the lower part of my seat.. (nothing in the steering wheel) so it feels like a u-joint, over 40 it disappears and if I'm in second at the same speed, no vibration.
another vibration comes up around 55-60mph and gets worse the faster I go
I looked and the driveshaft is tight and where it's supposed to be. If I move the front u-joint up and down there's play where the drive shaft is splined to the transmission (but I'm assuming that play is normal - though does anyone have an idea on what normal play there is (d/s to tranny)
And the driveshaft doesn't have a carrier bearing in the center of it.
So I suppose my questions are:
- Anyone had this happen to them before? Ideas on what it might be?
- I was thinking of checking the motor and transmission mounts and if they're ok, getting the driveshaft balanced.
anything I should do first?
Thanks
