Hi All, sincerely appreciate your help narrowing down the cause of this.
Friday after a 45 minute highway ride in our 2003 Subaru Outback 3L H6 VDC I noticed a burnt smell which smelled much stronger than the typical hot tire smell. When I checked around and under the car, I traced the smell to the front right tire/tire well. I could not find any evidence the tire was chafing against anything, or any evidence of any fluid leaking in the tire well or in the engine block on that side of the tire. The smell is stronger and more pungent than the typical hot tire smell.
Would could the source be? Car is in great shape, we have a great mechanic - honest, sharp and a good value, but before doing the rounds of mechanic, tire rotation place and alignment place (all 3 different locations), would be nice to be able to narrow it down.
Some things I’ve thought of:
Leaking fluid that I’m not able to see which is falling on a hot part in the right side of the engine block close to that tire
Problem with brake fluid and brake pads causing the brake bads to close up much harder on the right front wheel
Brake fluid leaking near the brake pads in the right front tire well
Tire alignment issue (Though I had the tires aligned about a year ago, probably a good idea to do again now - manufacture says it’s unnecessary to do frequently but on an AWD vehicle I think it should be done once every 6 mo. to 1 year. However, on on a previous alignment after a tire rotation when a front wheel was off alignment there was no smell like this).
Tire rotation - I’m a little past due but not much, but don’t understand why the R tire alone would act up, and before previous rotation never had a smell like this.
