New to the site and was wondering if anyone could help. Installed the 4" Rancho suspension lift on my 08 fx4. Looks great with the 35x12.50 tires but get a knocking noise from the front whenever I turn the wheels hard or when braking. Called Rancho and they have never heard of this problem. Can anyone HELP?

 

you got everything bolted down nice and tight?

 

actually took it to 4wheelparts in nashville to have them take a look. Said everything looked good and only had to retighten 1 bolt. Still made the same noise when i was backing out of their parking lot. Glad they didnt charge me for not finding the problem

 

thats odd.... jack up each side one at a time and spin the tires and turn them and spin them etc.. see if maybe a cv axle is having a problem yea i know its a 2008 but still stuff happens..

 

I appreciate the help. will have to look into it tomorrow morning. Let you know what I find out. Last time I took it in for services they said that the new steering knuckle was making contact with the lower control arms. Dont see how that could make the loud popping noise that im hearing, but its worth taking a look while im under there

 

yeah just make sure u jack up on the control arm... just soo the suspension still have a load on it... its almost like maybe somethings binding up on you.... maybe a balljoint...
