80K miles, slight shimmy.

2008 4 door with 80,000 mostly road miles. I sometimes have a slight shimmy, back and forth with the steering wheel, when driving straight and it increases under braking. The brake rotors and pads are thin. Will a brake job fix this? Also anything else I need to check with this mileage?

Get under the jeep and check the torque on all suspension connections. Also check the condition of bushings. Probably need to change your upper and lower BJ's. Change brake pads and runout on rotors.(probably need to be turned). Air pressure on tires and have them rebalanced. There, that's not too much, is it. Might do a search for Death Wobble by Planman.

Could be a bunch of things given your mileage. Could be a bunch of things. Tires...brakes maybe...have to start ruling things out. Is the shimmy speed related?

How do you know the rotors are thin?

As mentioned, check torque on all suspension components and do a check on your ball joints.

Thanks all. I recently inspected the rotors and pads while getting 4 new tires, the brakes are due for replacement. After the brake job, if the shimmy is still there, I'll get her to the dealer.

I think that a pretty common issue on these are the tie-rod bushings wearing out, especially with that many miles.

If it shimmy's before you brake then your brakes are not the cause. As said many things contribute but at the age and mileage I would check the track bar bushing first, then the tie rod and drag link next

Thanks to all, I will get them checked during the brake job.

Should I go with stock parts or does the aftermarket have some higher quality parts?

It really depends on your lift and set up. We recommend the Rock Krawler Bomb proof track bar as the replacement. AT $149 retail it is the best we have seen and it is double adjustable so it goes on lifts from 2.5" -5.5"

Also, be careful as most mechanic have NO clue what they are looking for. It's a Jeep thing.
