odd wobble at 60

began · 02-02-2011, 02:06 PM

okay i have an odd wobble at 60 it only happens from 60-65MPH and then stops. I had all the tires balanced and it still does it. checked over all the bolts everything is tight. any suggestions? i recently replaced a unit bearing could that be causing it?

this is with my stock (girl) tires not swampers

Sounds like cruise control :)

Did you toss a weight off the rear driveshaft, or ding it on -Oh, I don't know- a rock or something? (might be worth a balance at the DS shop?)

Have you had the driveshaft apart? Is it possible that the driveshaft is no longer "in phase"? (U-joints on each end no longer perfectly aligned, off a spline more in the slip?)

I'm trying to go for the little things that would not be noticed for the vast majority of the useage...

Was the replaced unit bearing off brand crap, or quality stuff... I've seen some unit bearing testing where they sucked right out of the box... :confused: Maybe just the other old unit bearing whining about the attention payed to the other side??

That's my $.02

Check your tie rod ends. I had a death wobble at 45 with my 98 f150. Turned out to be tie rod ends. They were so loose and worn out that it practically fell apart when I took them off.

okay so i checked over the drive shafts all look okay nothing missing, checked for play in both unit bearings both looked good, checked all the tie rod ends still looked good... i didnt get a chance to get up to speed but ill update tomorrow.

put the swampers on and see if its still there.

Maybe a more sophisticated tire balance is instore. Some times the radial run out is to bad for a regular balance to take care off.

swampers are horrible for balance..me and scott have ben fighting with them ever since i got them. I rotated the tires to see if it was just one that is out.
