Front end pop and hum.

[dkchrist]

Alright I have an 03 ranger with the RCD lift on it and now I am getter a pop when i turn full to the left and the suspension cycles a little the front end drivers side pops like something is unloading. Also when i drive there is a low hum as well as a rubbery squeak. All of this is located on the front drivers side and happened after being lifted Front drivers wheel bearing replaced to combat hum but to no avail. Any help would be appreciated because i hate letting others work on my truck because normally something else comes back screwed :fire: Thanks for your help!

The popping may well be your lower control arm bushing. I have that same problem right now myself as I turn left and cycle the suspension. The other problems i'd have to guess...rubbery squeak could be sway bar bushings...hum if not the bearing assembly I'd guess front driveshaft since I imagine you had it lengthened...

Actually no front drive shaft right now so i know that isn't it. On the lower control arms if you tighten the bolts does that help? Also on the pop it will only show up if the truck is in motion.

I suppose it could help to tighten the bolts but if the popping sound is your lower control arm bushings it is because the rubber bushing has worn down and metal is contacting metal when you turn.

The pop on my truck will only show in motion as well. I think it has to do with the type and amount of force exerted when the vehicle is moving, suspension is cycling and wheel is turned.

One thing that may help lessen the pop is if you have your front swaybar removed put it back on.
