When it developed into full DW a couple times (gradual right bend in the road, with some bumps, at speed, set it off) I knew I had to track it down. All components appeared tight, tire balance was OK. I went after the front LCAs. The stock bushings looked OK (for 48K total miles) upon removal, but the fit on the bolt was sloppy, and the position in the slot was not as dead-on positive as it is with Blaine's washers.
Bottom line: steering feels more positive, and my shakes are gone.
It worked for me... YMMV
Thanks Lynn for the detailed information! Besides getting rid of the DW, did the ride improve with the LCA's?

Water Dog Normally, driveline vibes wouldn't go away with more speed, they would get worse. Are you feeling the vibration in the steering wheel or in your seat?

Close up pics of the steering components might help, too.

Well wobbles are usually more associated with the steering. Do you feel these vibes/wobbles in the steeringing wheel mainly or through the body of the vehicle.

Exactly what kit did you get?


If wobble I would check your front steering components. Do you have a drop pitman arm? Check the Tie Rod Ends? Did you have alignment done? Any steering Upgrades? Stock control arms?


If it is more of a vibe I would say that it is a drive line issue. SYE/CV-Driveshaft or T-Case Drop or what? Did you adjust your pinion angle? Tires Properly Balanced?

Need to give a little more info about your setup so we can effectivly help you.

drdexter33 The lift is 3-1/2"

I believe they put control arms on.

Any radial run-out on the wheels you purchased? I once bent two wheels on the trail, and I could not figure out why my (new) tires did not balance. Wobbles occurred at ~50 mph.

Also, did the people who aligned your front end actually reTIGHTEN all of the hardware? Are your swaybar links good and snug? Are your tires inflated at the same psi?

Then wheel balance it not the issue.

Neil F. Very common for wheel balance and wobble in the 50-60 range.

What about getting DW after going over a bump or series of bumps going between 40-55? The vehicle shakes violently and I have to slow down and pull over if possible.

Is it a wobble or vibration?
