I had a hino truck 268 replaced the rear suspension bushings but still with vibration

if your sure tires are balanced --start looking at hub/wheel bearing c/v axle -if good check suspension upper lower ball joints control arm bushings sway bar steering unit

Sounds like it could be upper control arm bushings. Vibration at 60 will either be a tire that is out of balance or worn from driving with worn suspension components

This could be a number of problems.... First one of your tires could be unbalanced(any tire shop should be able to fix that for a small fee). Second, Shocks could be bad and need replacing. After that you have all kind of bushings in the front end that could be worn out, but I would start with tire balancing and shocks.

Good luck

I'd have to check your suspension. You think the tires are ok? Did you try rotating the tires to see if it made any difference?

You need to have someone look at it that is experienced in NVH (Noise, Vibration and Harshness). Front end vibrations can be caused by many things. Each possibility needs to be systematically eliminated to find the cause. Someone who is experienced in this can eliminate several possibilities by simply driving the vehicle...Did the tire shop even bother to road test it? I'll bet not!

Sometimes INTERNAL tire problems can cause a vibration that cannot be found (or eliminated as a possibility) by putting the tires on a balance machine. To eliminate this as a possibility, rotate the tires front-to-rear one side at a time then drive the vehicle to see if the vibration changes or "moves". If it does, then the tire that just got rotated to the rear is the problem.

Also, the vehicle can be run on a lift to see if the vibration can be duplicated in the shop. Many times, if the vibration is being caused by a drive axle or CV joint, it can be located by running the vehicle on a lift this way. In the case of 4-wheel drive vehicles, it will be necessary to engage the front axles to get them spinning on the lift.

The entire steering and suspension system should be checked for looseness in the tie rods, stabilizer links and frame bushings, control arm bushings, etc. Any looseness in any of these parts can cause vibrations at certain speeds.

I have also seen vibrations that act similar to a tire being out of balance that occurs when the brake rotors loose a balancing weight on some vehicles. This may or may not apply to your vehicle, (yours may not have balance weights in the rotors) but this type of vibration can usually also be verified by running the vehicle on a lift.

Check your U-joints, all suspension bushings, driveshaft, stabilizer bar. Has the vehicle ever been involved in a accident, hard curb hits, extreme driving, off roading??

Possible causes:
out of balance/bent wheel/tire out of round
damaged or severely worn suspension components/frame
steering stabilizer (like a horizontal shock absorber) if applicable
steering box or rack needs replacement
front end alignment
worn ball joints/ macphereson strut assembly
-these areas are where you should start and eliminate possible causes

Try replacing the end links to the front sway bar. The sway bar end link bushings may be worn and needs to be replaced, buy the sway bar end link kit with the urethane bushing. They last a life time and cost about $45.00 for both sides at Parts Source or Auto Zone and takes you less then 30 min to repalce both sides. Good Luck and keep me posted. Worn bushing to the sway bar, shocks and steering component will cause vibrations out on the highway.

Hi vibration at 60 is normally wheel balance not the alaignment, get the 2 front wheels weighted and balanced, if they are wearing unevenly then it could be suspension bushes,track rod ends.

But most likely the wheels just need balancing only cost about $20 to 30 max

Hope this helps

Start by inspecting your tires. Look at tire ware, any tire separation (bubbles). Look at you wheels to see if you lost any wheel weights. Look at your driveline, wiggle it at the Ujoints to make sure they are tight. These are good starting points.
