driveline angle

[01Cobra]

I'm trying to find a shop that can solve my drive line vibration that I believe stems from improper angle. I had my diff bushings replaced which reduced the amount of vibration transmitted but it is still there. I really believe that my trans/pinion angle is off but I don't know how to go about solving it. Any thoughts?

When does it vibrate...all the time?...highway?

how long has it been doing this? since u got the trans replaced?

You can feel it after 80mph. I just noticed it one day when I ran the car through the gears and started to get up in speed at about 80-85mph. And now that Ive driven on the expressway a few times Ive noticed it. I just want to get it to where it needs to be so it doesnt vibrate and I dont run the risk of wearing out other components on the driveline.

vibration

have you tried rebalancing your drive shaft?,sometimes you just have to take it off and turn it to a different spot.

 

[01Cobra]

yes, then I ordered and put on a brand new driveshaft from ford

Drive line vibrations a really hard to fix. I dealed with a nasty problem with my 03. (turned out to be a bent input shaft) Any good shop could find the problem. Replacing/guessing at parts doesn't slove anything.

When your driving, push the clutch in, the vib should go away. If it doesn't then it is not a drive line problem. A very close inspection of the car will also help narrow down the problem area. Any funny noises coming from the car?

Does the car have a gear in it or ever have the diff opened up?
Did you have trans work done to the car?

not entirely true,
if its a bad ujoint, poorly balanced shaft, or improper pinion angle it should not be affected at all by pushing the clutch in

Im looking for someone that can check all this for me and get down to what I got going on so I can fix it.

d/s was my problem

You need to check your pinion angle. If you can't do it yourself, take it to Speed Inc. I doubt that's your problem though. I've never heard of pinion angle causing a vibration.

I Just thought I would let you know that I had simular issues right around 75-85 mph but it was from my HUB CENTRIC rear wheel spacers that were not so hub centric:lmao:

Just a thought to consider if you have them also.

There is a good driveline place in Villa Park called Suburban Driveline.... I am sure they could check it out for you.

If you have not messed with your control arms, I would doubt your pinion angle would be off... probably something like a driveshaft or wheel bearing.

I had this problem with my car too, ended up being my trans mount... but it would go away when i pushed the clutch in

you forget the enormous tolerances on these cars
the irs cars are especially prone to the pinion angle being off from my understanding
could also be your trans mount, but not all of us have cars a billion years old like pj's

Might be worth a shot to remove my eibach hubcentric spaces and see what happens.

 

[Fast99Snake]

i would try that first
these cars are prone to high speed vibes though from the poorly balanced d/s to the misaligned pinion angles
