Subaru Repairs | Almost every car on the road has a front lower control arm. This is a critical part of the front suspension that holds the front wheel in place.

Subaru Timing Belt replacement | Subaru Engine failures

Subaru Timing Belts | When it comes to buying or maintaining a Subaru, “When was the timing belt last changed?", is often the first question I ask.

The EJ series of Subaru engines uses a rubber belt to synchronize the camshafts to the crankshaft. This covers pretty much every Subaru 4 cylinder motor from the early 80's until about 2015, when the new FJ series came into production. If this belt fails, the engine will not run.

With some of EJ motors, a failed belt simply means a breakdown and trip to the repair shop to have it replaced.

Engine Failures | The B205 and early B235 (1999-2003) Saab engines had high sludge problems, which is a common killer of these motors.

What is sludge? Sludge is excessive buildup of hardened, burnt, and old oil deposits, which was even a problem when these cars were new. There are a variety of reasons why this happens and why it kills, and there are plenty of ways to fix and prevent this from happening to you!
