quick question guys I'm having some trouble on the highway with me jk. Every time I go above 65-70 I get this like violent shaking in the whole jeep. Not uncontrollable steering is stable, its just not very comfortable. also worth mentioning i have 35 trail grapplers. not sure if its just mud tires don't agree with the highway? or is this like a balancing/alignment issue that i need to take back to my installer?

 

If steering is stable, it sounds like a wheel balance issue. Get it checked soon. You don't want that thing to bounce too long.

 

Yep x2 on that.

 

X3. I've lost balance weights before when offload. The vibration/shake at a certain speed (50mph) in my case) was the result.

 

This sounds like a number of things with the simplest being a tire balance required. If your jeep was recently lifted you may want to check your track bar to make sure it is tight as this can cause some shaking, or as it is lovingly known as Death Wobble. There are a lot of threads on here that will help you trouble shoot what you have so do yourself a favor and read up before you let that get any worse. Planman has a great write up on Death Wobble so search by his name and you will find it.

 

Not DW. DW wont typically occur at those speeds and it would become rather uncontrollable, unlike what the OP mentioned.

Did you just have all this installed? What are you running for drive shafts? Any noises associated with these events?

 

Yea i had it installed at a shop close to my house. Ill give him a call tomorrow and get him to rebalance the tires and go from there

 

Check your front drive shaft

 

still running the stock driveshaft?
