Hi all,

I am solving a few different problems on my 300D, your help is very much appreciated.

-I need new outer tierod ends. I see they are available in left or right-hand threaded. I assume I purchase one of each?

-I need lower control arm bushings. I read somewhere that W126 bushings are compatible and easier to install, is that true. Also, what else should be replaced when doing this job?

-My brake warning light, parking brake, and low-volts light all stay on when started unless I tap the gas or pull the parking brake. Additionally, under a heavy load (lights, radio, blower), the battery reads 12.5v, under no load it reads 13.6v - is this a bad voltage regulator?

-My #4 cylinder injector hardline keeps filling with air. No fuel leaks, but after the car sits I have to bleed the line for a few seconds and it runs better. I assume I need to replace the line? I inspected it and I couldn't see any cracking, but, it's probably small.

Thanks very much!
