I have a 2006 Ford F-250 Super Duty, gasoline V8 5.4L, automatic transmission, rear-wheel-drive. When driving on the highway, a burning rubber smell developed. I got the truck home, then to the shop, as soon as practical.
Prior to this burning rubber smell, there had been some noticeable issues with steering, reminiscent of a problem with tie-rod ends. The repair shop thought these two issues were related, and they determined that there was a problem with the wheel bearings and the grease surrounding them. The deficiency in grease, they thought, was causing the burning rubber smell and the steering issues.
After their repair, the steering issues are much better. However, the burning rubber smell remains, and it seems to be coming more from the engine compartment anyway. The belt appears to be fine -- no noticeable wear and tear, etc. What else could the problem be?
Thanks for your help!
