I followed Kent's instructions the best I could in his Vacuum Diagnostic manual. Here is what I did and what readings I got: following the main black plastic line to the firewall, there are several lines that split off. 5 in total, I believe. I unplugged the four smaller, colored lines and plugged them with golf tees. The remaining line is actually some sort of plastic housing unit with a curved rubber hose attached. I took my measurements from this point and with the engine on, I got a measurement of 10 psi from my mityvac. I think this means something is up with my vacuum pump, unless I performed my measurements incorrectly.

Is there a trick to removing the front ABS sensors for cleaning other than removing the single bolt? The sensors do not readily come out and I don't want to apply pressure and break them.

Kent,

I have read your manual for the replacement of the steering lock + tumbler and purchased all the parts I need. I have a steering lock from a very well maintained 91 420SEL. Can I use the alarm buzzer from that one for the steering lock of the 83 300SD? It is different in that it allows for one more plug than the one on the 300SD - but the other plug looks the same.

Thank you
Dieter
