Hi,

Here is my question:

We have severe tire thump, It does not matter if we leave the driveway or were driving eighty mph it is just a loud thump, thump constantly.

I just thought it was bad tires, as we had winter tires (Blizzak) until now.

We replacement them with used Goodyear's we had from another car (same tire size) but the tread is perfect, the noise is still there today.

It is like we just wasted $80.00 to have them mounted and balanced. My only guess is a bad wheel bearing or warped rotor. It is the passenger front side.

It does not matter your speed it is just a thump, thump.

I am just lost and thought I would ask here for some help.

Thank you

First thing I would do is swap that passenger front with the one behind it in the rear.

See if the thumping follows that tire to the rear.

If it does, you will know that it is the tire that is the problem.

If you are limited with tooling (like jack stands), it may take a little longer to do.

1) Jack up the front wheel, remove the suspect wheel and replace it with the spare.

2) Move to the rear, swap the front with the rear.

3) Then back to the front and swap the spare with the rear tire

This will require a little bit of labor, but you have spent no money for this test.

Return with your results.

Hi,

Thank you for your reply, it would take me a few days to complete that. I had a scare a few years back using those small jacks and the car rolling backwards because the driveway is on a hill.

Did not even get to jack the car high enough for the stands and she rolled.

I Never did buy the three ton jack like I wanted.

About the noise, prior to removing the tires from the old car it was quiet and I store them stacked to prevent flat spots.

I will try to remove the tire myself or have the dealer find out next-week.

Okay,

If you try it yourself,

Chock both sides of a wheel so that it cannot roll either way as you lift.

If your driveway is too much of an incline, find you a nice shady spot in a park/ parking lot.

After all, it is just switching wheels around, not removing your transmission.

If you make it look like you are having a difficult time with it, sometimes a good Samaritan will jump in and make things a whole bunch easier!

Just be safe in performing the task!

Return with news!
