Oil filter wrench you may know more

An oil filter wrench is a tool for removing spin-on type oil filters. These filters are smooth, cylindrical canisters with knurling on the bottom that are difficult to grip, especially when they are oily.

One common type of wrench is shown on the right. The loop of chain is placed around the filter, and the bar is turned anticlockwise by hand until the chain wraps itself tightly around the filter. A socket wrench or adjustable spanner is then used to turn the hexagonal bar further in the same direction. This increases the tension in the chain, which bites into the soft metal casing of the oil filter which helps prevent slippage.

Another type uses a metal band that is attached at both ends to a handle. The looped band is placed around the filter and the handle is turned anticlockwise, which puts tension on the band, causing it to grip the filter.

A third common type of wrench utilizes a metal or plastic cup that is shaped much like a socket. The cup is placed on the end of the filter, which engages the knurling. A socket or wrench is then used to loosen the filter. Volkswagen Group and BMW cars require this type of wrench to remove their filters (or the lid of the filter housing, where a non-cartridge filter is used).

What is ball joint separator?

We are ball joint separator manufacturer and we will provide some knowledge about ball joint separator.

The first signs of a failing ball joint include loud banging over bumps and/or sloppy steering as the joint separates out of its socket. A typical safety inspection should measure the amount of motion in your ball joint, and only allow a safe amount to pass. You can test ball joint play yourself on McPherson spring struts that do not put any load on the ball joint by lifting the car and manhandling the wheel. This design is rare, however, because most suspension springs apply constant pressure on the assembly.

If your car has a spring that puts load on either the upper or lower ball joint, you will need to remove that spring pressure by positioning your jack under the control arm and jacking it a few inches up to relieve the spring pressure on the ball joint. If the design allows, you can use a special ball joint support tool like the one made for the Saab 900 to hold everything in place. You can also relive tension with standard spring compressors, which is a common way of doing this.
