I have an 2007 JKU 4door with a 3'' lift. I'm running with 265x70x17. I like what I have, but I'm realizing when traveling on rough free-way or streets that the Jeep gets a very Violent vibration almost ''shaking like'' feeling.

Took it to a local 4x4 shop and they want to replace upper and lower ball joints, the tire rods, and rebuild the steering gear box almost $1500 plus more depending how the steering box looked!?

Then I took the Jeep to local repair shop. The owner of the shop said I do need both upper and lower ball joints(really the lower, shop recommends doing both because all ready be in there) but not for another 20-30,000 miles, ball joints have small (very) movement and recommends bigger tires to compensate for the 3'' lift.

Any recommendations or 2 cents would be help-full.

If needing tires, any site I should be looking at besides Tire Rack?

Thanks! Semper Fi and God bless the USA!

 

Call Northridge and order a full set of synergy ball joints (itll be a lot cheaper then letting a shop provide the ball joints), then call a couple of OTHER shops for an install quote.
Don't do anything else until after the bj's are installed and you've driven it.

Quick edit: it may be poly performance instead of synergy, I always get them confused... Potato tomato

 

Thanks man! I'm calling now!

 

haha no idea why he would recommend bigger tires to "compensate" unless he was going to be the one selling/ installing them lol. But yeah ball joint movement is no good.

 

LOL I know it seems odd. He started talking about the lift I had with small tires that it was off balance (symmetry)? Um, yes he did ask to do the tires but told me to go to Tire Rack . Com and just charge for balance.

 

They'll probably want damn near 400 bucks to install ball joints. Try a track bar. If your lift didn't included a m ew one get a aftermarket adjustable. If it did..loosen and retourqe to spec with loc-tite. Ball joints are probably a good option as well
