Which rubber and plastic parts would be changed?

798 Views 6 Replies 6 Participants Last post by  jrogosich
When I finally find a 300D in the right condition and for the right price I'd like to proactively replace rubber and plastic components, filters as well as any other components likely to fail so as to start with a clean slate.

On my list thus far:
Window and door seals and runs
Sunroof seals and pads
Brake rotors and pads
Shift bushings
Flex disks
Exhaust suspension 'doughnuts'
Air filter and elbow seals
Glow plugs
Oil filter
Voltage regulator

Could anybody help me compile a list of all the hoses, seals and other bits and bobs that would be prudent to preemptively replace in the engine compartment and elsewhere?

In my opinion, your list is right, but replacing windows, doors and sunroof seals if the old parts are in good condition makes no sense and can actually cause problems. If you want, buy those seals, keep them and only if necessary, replace them. As said in the previous post, replacement parts today aren’t as good as the old ones and won’t last as long.

Don’t worry about replacing every possible part that may or not be worn. Before replacing, visually inspect and drive the car for a few weeks so you can determine its needs and address what really needs to be fixed.

Also, I would add to the list flexible brake hoses, fuses, injector return hoses, cigar hose, diesel filters, power steering filter and transmission fluid, filter and pan gasket.

And don’t forget to check (and replace if necessary):
-Axle boots and drive shaft bearing and carrier bearing.
-Ball joint, tie rod end and guide mounts dust shields.
-Coolant hoses and expansion tank.
-Radiator cap.
-Condition and type of the coolant.
-Engine and transmission mounts.
-Differential mount.
-And any fluid that you don’t know how old it is.
