Hey guys, I’m having a shimmy when cruising on the highway and hitting indention or bump in the highway at anywhere between 80km/h and 100 km/h (~60mph) i have momentary shimmy only right after i hit a bump I’m not sure if it makes difference if I’m hitting it straight on or if I’m hitting the bump while having the wheel slightly turned (curve).

suspension is rather stock: I have a skyjacker steering stab, and aftermarket moog greasable TRE, greasable balljoints. everything was changed less then a year ago.

the tires i have on now are stock size 255 70 r 18 on stock share rim, they are arctic claw tires not sure what rating they are at..

there are not wobbles or shimmy when driving at whichever speed, it only shows up right after i hit a bump in the road at moderate highway speed.

The sensation is of the steering where shimming back and forth, i don’t need to slow down, it usually stops doing the shimmy shorty after (1-2 seconds) without the need for me to slow down or anything.

Any help?insight? where do i start looking? what more info can i give you guys?

Thanks!

IMO any time something like this happens first thing to check is the tires,,,balance and rotate from front to rear...in this circumstance I would move BOTH front tires to the rear.moving just one it is possible it will still be there and may give a false sense of okay not the tires....if possible get the spare in the mix.....the more variables/ tires that are tested on the front the better.... it leaves no doubt that it is something other than the tires if it never goes away....GOOD LUCK!!
