Front end vibrations

[GX4SEVEND]

So while driving at highway speeds, my 4runner has a very annoying vibration to it. Anything over about 50mph and it starts to vibrate. Right around 60 is where the magic happens. It has this resonance that literally vibrates the keys hanging from the ignition and all the change I keep in the cup holder.

Little info........

Tires balance two different times
Alignment done this morning
Lift is in the sig
Brand new cv joints
Lbj, tie rods checked out fine



I'm not sure what else it could be. Someone suggested using weights on the outside of the wheels instead of the inside because it's more accurate. Guy at the tire shop said it could be from using a 7" wide rim on a 315 tire. But a couple of guys on here have done it. Brian2sun is even running the same rim, same size tires and even the same color rig haha.


Any ideas?

it could still be the balance, do they have weights on both the inside and teh outside of the rim? here's a good explanation of why rim choice and having a good shop with the right equipment is important
Vibration Problems

short of that all i can think of is wear patterns, as the problem you explaining is most commonly associated with wheel balance issues.

The weights are only on the inside right now.

I know this is an old thread, but I was just wondering if you had ever figured out your vibration issue.
I have a 2003 4Runner LTD (4.7, AWD) with a similar issue... which is driving me crazy! Back around November/December I replaced my half-shafts, due to both inner boots being torn, and getting a humming/vibration type of noise. Recently I started getting the same noise. I checked the front brakes and found both calipers had seized inner pistons. I replaced the calipers, rotors and pads... but the noise I'm hearing is still there. I was just wondering if your issue turned out to be the half-shafts; because I'm wondering if it is possible that mine went bad...again. Thanks.

Broken belts in a tire will do that. They can balance fine at the same time.

could be a lot of things, bent wheel, hit any curbs, pot holes ect of late? busted belt?

drive shaft thrown a weight? or got dented, how about maybe missing a driveline bolt?

bent rear axle?

can you tell if its coming from the front or rear?
