The Porsche 944 was built from 1982 to 1991 and was manufactured on the same platform as the 924. Although it was intended to last into the 1990s, major revisions planned for a 944 "S3" model instead brought out the 968, which then replaced the 944. The 944 was a successful Porsche model in the United States. However, because production of the car had stopped, these cars would be sold with used, aging Porsche 944 parts. For those looking to buy a used Porsche 944, here are some things about car parts wear to take note of.
The most basic problem with the alloy control arms is that the ball joint keeps riding inside a nylon cup or sleeve, which is inserted into the aluminum housing of the control arm. This, in itself, is not a huge problem. However, because of the geometry of the control arm, spindle, and ball joint housing orientation, a pre-load is created. This prematurely wears out the nylon cup, housing, and ball joint pin. When the pin is worn, it develops cracks and shears completely. This problem is more prevalent if the Porsche 944 had been driven extremely hard.
As the Porsche 944 becomes more inexpensive to buy, many owners have put off their car's maintenance. However, components like the timing belt is not an item that should be neglected. When inquiring about a used 944, ask for a record of its repair and maintenance history. If the owner doesn't have any, ask how long ago the timing belt was last checked or replaced. This component has a lifespan of about 30,000 miles.
For those who already own a Porsche 944, know a little about servicing the belts, or look for a mechanic who can do this work well. Failure to maintain the belt could result in the component turning faulty.
While this is not a major issue, the water pump is a component that can and does fail, and in a car like the Porsche 944, there is a fair amount of work needed to get it replaced. Some owners take it as a wear-and-tear car part and just swap it out at the same time they change timing belts. Some might find this an overkill, but it's a workable, precautionary detour that can help Porsche 944 owners avoid some hassles.
