I have a front end shake that is the same regardless of tire age. I can't find it. My steering is fine, tired are wearing pretty evenly. This is with the hubs unlocked or locked. I can have the tires rotated and rebalanced and it is exactly the same. Running American Racing wheels. Making me crazy.

Spindle needle bearings? Mine shook in 4wd and they made a world of difference...

Front u joints?

Don't think it's the front u-joints because it happens even when the front driveline is free-wheeling. I suppose it could be either the king pins or bearings.

All speeds? My king pins caused a really bad shake from 35-40mph and minor shakes as they got more worn before I did them.

Smooths out at about 75 MPH. I may have multiple issues...

I've read that the front u joints can still have an effect, even when free wheeling.

I've got to do my kingpins this summer as well, so I'm going to do the u joints while I have it apart...what's an extra $40 in the mix, eh?

Are the tires round?

I know that sounds silly but I've had similar issues in the past where I failed to rotate the tires regularly.

The next time you've got the truck in the air, check the run-out of the treads.

(It couldn't hurt).

I started my truck and twisted the borgesson while looking at the front end. The tie rod link on the drivers side had at least 1/8" of slop, and the other side and drag link ball joints were also shot. I replaced all of them and got rid of the shake, but I still have the shimmy at speed. I just ordered a complete kingping rebuild kit and the 3/4" hex wrench to get the uppers out. I can tell my king pins are shot because it is wearing the inside on the tires a bit. Have a feeling I will have to put a 6' cheater on the hex wrench to get the things loose....

The steering is nice and tight now though!
