lift kit

I installed a 3" lift kit on my 07 reg cab 4x4 and now I get a noise after 55mph and it goes away if I step on the gas or let off of the gas?

 

drive line vibration?

 

That's what you get for doing your own lift!

 

I did my own lift.

If you've got drive line vibs, you probably just need a shim in the rear. More info is going to be needed though.

 

So what other info do you need? all I put was a coil extension on the front and an add a leaf on the back!

 

Changing the geometry of a factory suspension usually creates problems, and then require more modifications, which might create their own problems. Welcome to the exciting world of 4-wheeling

With a 3" lift on the front, your CV axles are likely at too much of an angle. If so, then lowering the front diff might fix that.

 

I like all these expensive "theory s"

 

Try adding a center bearing drop to drop the driveshaft. New UCA's if your at 3" up front wouldn't hurt either.

I did my own lift too and don't have any vibes.

 

Useless on a 2nd gen.
