How do I change rear breaks on a 2003 tracker 6cyl 4x4? the axle is in the way...
I found my noise wasn't something loose. It was the rear strut was bad. Was more of a load squeak that sounded like something knocking.
Did they change the fuel filter and the air filter as well. Odds are they didn't replace the fuel filter as they're kind of a pain in the rear to get to.
There are reasons that front breaks are more expensive. It may be more expensive to replace front breaks more then rear breaks, because the uses front breaks more.
