I have been reading alot on here about the DW and I don't have that. I read that it could be the tires out of balance and it could be tie rod.

I have a 09 4 door 6 speed with 2.5 lift with about 6k on it with 35's and about 5k on the tires. I run 26 PSI and it just started to do this shimmy about a week ago. I got under it and re check the torque on everything and its all right to specs. Anyone had this happen? And know if it is tire issue??? I had 1st-3rd gears and syncro's replaced by dealer, around the time it started this. Could a loose transmission mount bolts cause this? would it make the steering wheel shake?

I thought it was the tires at first but it feel it in the shifter, so it is coming from the rear and the front?

Any ideas, besides check the torque on the trans mount and re balance the tires?

 

on the shfit knob my jeep does the same thing. it gets worse if you have an aftermarket/heavier shift knob or when you are running WOT.

If i hit a bump and get a bit of wobble in the front end the shifter hakes too. it happend when i had a tire out of balance also.

 

The shake is when I am driving with no bumps. I went on the smoothest road I could find and it still make the shake. I was a dead flat road too. The shake in the shifter isn't the normal shake its a shake that go's along with the shake of the steering wheel. And stock shift knob.

 

You chould check the torque on the trans mount, but may be more of a tire balance issue. Try rotating your tire's to see if that change's anything. I have had the same problem with my 09 JKU. Which started in Nov of 2010, 5 months before I put my Lift kit on. when I had tire's rotated it stopped.

 

^^^This - and when was the last time you had your tires balanced? You might have just thrown a weight or some other balance problem. If the shake is speed specific, that is what I would look at first.

 

i was thinkin the same thing, maybe ya lost a weight. or carrying some mud

 

My 08 JKU is doing the same thing. It's very mild, almost unnoticeable but it's there. I'll start with a rotation & balance. see if that helps then go from there.

 

Check the balance... The tires might need to be balanced, if everything else checks out...

 

my shift knob vibrates/wobbles quite a bit. figured it was just a jeep thing.

 

If the shift knob wobbles the issue is most likely coming from the rear...
