Vibration issue, tire related?

[Track Junky]

Tires I currently use I run at 30 lbs hot. I inflate to 36 lbs when car is sitting in the garage.

It could be tire related, but could be many other things. The odd thing is it is not constant.

You could try switching the tires from one side to the other and then back, because they're directional.

Check the sidewalls for any odd bulges, a belt separation that will get worse over time. The expensive part would be to replace the tires completely.

Do you feel the vibration in the steering, seat bottom or both? If from the steering wheel it's coming from the front, seat bottom, than the rear.

This is a difficult vibration to find if it isn't tires.

Good luck!

The vibration became consistent so I began chasing things down again tonight. Found a loose axle bearing in the driver's side rear. Pissed because it's a brand new part, just a couple weeks old but happy that I found it and it makes sense. Not knowing is worse.

I'll get a new bearing ordered tomorrow and get it swapped out later this week.

Lance, I'm curious, what bearing manufacturer?

Let me give the seller the chance to make it right before outing them.

Things happen, how you react to things happening is different though.

I now feel okay about calling them out. I ordered the bearings from Moser on 05/12/2014. I installed and drove on them the first time on 05/16/2014, have put 270 miles on them including 4 runs at one autocross event. Apparently Moser buys their bearings from Green Bearing Company and they do not come with any warranty whatsoever. If I want I can send the bearing back to Moser and they will try to get a replacement for me.

OR...

I can pick up a different bearing from a local Napa for $59.00...I believe it's an SKF bearing. According to Moser it's a better bearing but does not have the O-ring seal like the cheap arse Green bearing...

Or Auto Zone has a Timken

And O'Reilly and Advance Auto have a Federal Mogul National

Advance is $39.99, everyone else is about $59.99 for one. Moser charged me $65.00 for a pair...

I dont' care about the money, I want a quality bearing. One would have thought I WAS buying a quality bearing from Moser themselves... Shame on me for trusting them.
