Front End Vibration?

[elcidsurfer]

Got an '87 22RE 5-Speed and have some Front End Vibration. Here's the facts:

Cant hear it with the radio on loud
Cant hear it with the windows are down, only up
Only happens when cruzin 50mph or faster
Can barely feel it in the shifter and steering wheel
Just had a balance, alignment and break job with no probs
5-Speed shifts smooth and strong
22RE still gets 22mpg on my daily commute

Any thoughts? Front Drive Shaft? Wheel Bearings? Or is it just an older vehicle that has thin metal and no sound dampining causing it to be louder and rougher compaired to a newer vehicle and Im imagining things?

Thanks

Was it there before the brake job. Did they change out the rotors. If so they should have done wheel bearings also. They are in the rotors.

Does it get better or worse in 4WD? with the hubs locked or unlocked?

Start checking the front end parts (TREs, ball joints, bushings, steering idler arm, etc) for slop.

purevenom1,

Noise has been there since I got it a couple months ago, thats why I had the balance, alignment and break job done... Not only did it need it, but I thought the vibration might have been from either of those.

fourwd1,

I'll have to check it in 4wd. But I'm not sure I will be able to really test it since it only occurs driving above 50mph. Can the T4R's 4wd Hi Mode handle 50mph?

I'll also check all the front end components. Is the best way to support the front on jack stands so there's no weight on the components and just check for play in each?

Thanks fellas!!!
