I have vibration at 60 MPH
On my 98 2WD 4runner that has about 127k miles has a vibration when I hit 60MPH and higher. I just balanced the tires all around and don"t know if I should change the u joints. There is no movement in the driveshaft if I move it up and down and there is no clunking sound when I put it in gear. One thing I did notice is that the transmission mount has play in it, when I put a pry bar in between the mount it moves up and down allot but the rubber dose not looked cracked or damaged. Another thing is when I make a left or right turn it sounds like the wheels make a light grinding noise. Can any of these things cause a vibration? Just wanted to see what you guys think or if anyone has the same problem. Thanks.

the tranny thing could definately cause a vibration.. but after that you could have warped rotors.. are your tires worn down at all? sometimes that can cause it.. and a lot of tire places suck at balancing tires.. a bent rim can cause vibration too

My front tires need to be replaced soon and the front drivers side is worn on the inside. I just had the tires balanced at my local junior collage where i'm taking steering and suspension classes, and it was on the new hunter machine.

I didn't do the road force balance, maybe I will do that next class, its free and I get to learn how to do it. I don't really feel that much in the steering wheel, if I hold it tight it dose not shake much. I feel it more in the seat and floor.

if you feel it more in the floor and whatnot its probably that loose mount.. usually tires and whatnot you feel it more in the wheel, i dont know what those balances you are talking about but i work at discount/americas tire and we always balance out peoples tires pretty good too. id reccomend going there, they will most likely balance your fronts for free. it also depends on the type of balance you use, for example it looks like the best balance for your rims would be a clip weight if possible and a tape or sticky weight on the inside of the wheel as close to the face as you can get. and for the tranny mount im pretty sure its not supposed to wiggle or move.

When i'm at 60 to 65 and let off it will vibrate a little stronger till it gets under 60 MPH. If I replace the u joints should I have the driveshaft balanced?

I didn't have to have it rebalanced, there was an obvious chunk missing from the front u-joint. Interesting, because my vibration would mostly go away when I let off the accelerator. Also it lessened when I got above 65ish.

Going to order the mount today and see what it dose, then I will try replacing the u-joints.

Quick question:
Are you balancing lug centric or hub centric?
I "have" to go to the dealer to get the lug centric and all is good!
I have tried several other places that claimed to have the right equipment, but the balance was still off.
The toy wheels are centered on the lug holes not the center holes.

A bad wheel bearing could cause the grinding sound and cause a vibration. Also if the wheels had mud on them and was not cleaned off , it could throw the balancing process off.

You need to have the wheels
using the lug eccentric balance attachment. The JC tried to balance the wheels using the hubs as center when the lugs 9apttern of 6) need to be used as the center of the rim.

I vote ujoint.....check the driveline mounting flange bolts for loose ones also.
Have you tried lubing the u-joints?
When was the last time you did?

raydouble No I have not lubed the u-joints, I just got the truck less then a year ago.
Thanks for all the feedback guys, I think I will change the u-joints and tranny mount then move to wheel bearings and new tires, need new ones anyway. I will be going to Yosemite next month with my wife and 2 year old and want to make sure the truck is in good shape.
