shaking HELP!

[varam0928]

Whats going on subaru forums, first time on the site first time subaru owner. I have a 05 baja turbo and I am experiencing shaking.... I was told it can be an unbalance of the wheels a U joint or since I had no idea it needed the highest octane gas it could be the issue. The shaking occurs between 40 and 45 mph and then goes away. Please help!

Wheels out of balance or wheel alignment is probably the issue.

My 2003 non-turbo needed a new "harmony" part.
This sounds kinda of Zen, but this harmony wheel hooks up to engine belts and I think the cam shaft and minimizes vibrations.

Look at engine when running at idle and look at bottom of belts rotating around a wheel.
If belts are not running true and u see a wheel wobble, this out of balance "harmony wheel" could be the problem.

Bad tires or rims may also be a factor. Good luck.
