Why is my truck still vibrating??

[jman11788]

Ok my truck vibrates in the steering wheel and pedals at 70+mph. I just got an alignment done with steering rack bushing replacements and got tires balanced and rotated a few days ago. The truck tends to pull to the right and then sometimes will pull to the left. The vibration also comes and goes at 70+.

Sounds like a bad alignment and bad wheel balance. Get a printout of your alignment specs when you take it back to them for another look.

I'm in the same boat with ill balanced wheels and from what ive been reading the problem is the shop not using the correct adaptor. Our trucks require the use of a haweka adaptor because most shops try to use a hub adaptor that doesn't match the center bore on our wheels. The haweka adaptor should get the balance correct atleast.

Wheel Balancing with Haweka QuickPlate - YouTube deffinitly an interesting setup, now i just have to find a shop that has this

It's might be the balance or worn suspension parts. I had the same issue and them balancd multiple times. Once I did a full inspection on the front suspension come to find out the upper ball joints and upper control arm bushings and strut bushings were shot. (I had just got the runner a month prior). Cj80cruiser has it right. Most tire shops just try using a cone to center it on the balancer. Either a bolt on plate needs to be used or if the cone is used on the back of the hub where it centers with hub in the truck it should be fine aswell. The vibrating pedle might mean your rotors are slightly warped. I had that sme issue when I put got mi rig.

Here is a great recent thread:

lots to look for on this issue

 

[lude and rude]

another thing to check into would be to make sure your motor mounts are tight and tranny mount. plus check your driveline to make sure its still nice and tight and you dont have worn out u-joints. had a bad pedal vibe and truck felt a lil sluggish this last week driving over the pass so i checked everything. driver side mount was almost flopping around bolts barely had the nuts still on them, plus tranny mounts were snug but not tight. might help you with your pedal vibes.

truck pulling could also just be a tire issue (bad belt) but most likely is worn bushings/joints and/or bad balance.

Could also be worn/cupped tires. If you were driving on them bad for a while they could be worn too. I recently replaced all inner/outer TRE, upper lower BJ along with steering rack bushings and it drives like a different truck. Nice and tight now.

If you're feeling it in the steering wheel, I'd put money on the culprit being bad inner tie rod ends. If everything is still original, do inner tie rod ends, outer tie rod ends and lower ball joints all at the same time. It's easier to do them all at the same time, probably needs them all and the truck will be tight as new when you're done.

How good is the drive shaft that runs from the transmission to the rear axle?
I too had this horrible experience in the past, 65 MPH and the whole truck shakes like crazy. Did the alignment and wheel balancing and no luck. Finally installed a used 4runner drive shaft, and problem solved.

Try to locate a shop that has a Road Force DSP 9700,this top of the line machine will balance your tire under load and locate the problem whether it's the tire or rim.money well spent IMO.

Ok I'm feeling its probably this too. I took a loom under there and they look worn to kingdom come. How hard would it be to install them? Looks challenging.

It's really not bad at all. The biggest b*tch is separating the inner and outer tie rod ends and the lower ball joint from the outer. But you replace everything, you don't have to worry about that. You could probably do the whole job in about 2 hours in your garage.

Just for the sake of those that will try to locate one, it's the Hunter GSP 9700 Road Force Balancer.

Perhaps just as important, or maybe even more important than the machine, is an operator that actually knows how to use it.

I've found at least two tire stores that had the machine, but didn't have any employees that knew how to effectively use the machine. It's pretty sad as a paying customer, having to show the employee how to operate their machine.

Well you were right! It was the left tie rod that was shot. Although the installation was a pain in the ass to me, it was really worth it. Absolutely no more shaking, vibrating on the highway. The truck feels a lot more secure now. Thanks!!

No problem buddy. Glad you got it sorted out.
