Rust can make a lot of mechanic work harder, as I’m sure I’ve written about many times before. One of the things it really makes hard is alignments. Adjustment bolts can seize in suspension bushings, making it impossible to actually adjust anything. When adjusting front toe, the jam nut can be rusted to the tie rod, and the outer tie rod can be rusted into the inner tie rod, sometimes requiring the torch to loosen them.
Today’s throwback post is a little different than usual. This is a post that I was told I couldn’t post by the dealership I worked at the time. I no longer work there, so here it is. Originally posted November 12, 2015.
The cooling system is very important for a car’s engine. Combustion chamber temperatures can be over 1000 degrees, and the surrounding parts of the engine are hundreds of degrees. If the temperature isn’t controlled, parts can warp and crack, and ruin the engine.

Many new cars in the past few years are keyless start, requiring the key fob to only be present in the car to allow the ignition button to start the car. From what I’ve seen, the systems are pretty well designed and don’t have many problems. I had an interesting one come into the shop recently: it wouldn’t turn off.
Ask any mechanic, and they probably have a drawer or box full of old nuts and bolts. It may not be very often that they need to be rummaged through, but sometimes they can solve problems.
I was working on a used Subaru Forester, and found that it needed a rear wheel bearing. It’s a bolt-in wheel bearing, which are usually easier to replace than press-in, because you just have to remove the bolts and take it off, instead of having to the use a press to remove and install it.
