Sagging rear end on 1986 300SDL ??

I realize that rear ends tend to sag with age, but there are relatively simple operations for that problem. With my 300SDL, it seems to be a more difficult problem. I continue to sag even after replacing my differential mount and having OK shocks on the back (i didn't change them, but they only bounce once after compression.) Should i replace them anyway (they probably have not been replaced in a while)? or are there other common wear parts that i have neglected to replace? I would really like to see tops of my rear tires.....Thanks for the help.

1985 300SD Burglar Alarm problem

How do I disconnect, turn off, or otherwise disable the burglar alarm in my 1985 300SD ? I had to go through deep water (8"+) at slow speed. Shortly thereafter, when I turn on the lights at all, the burglar alarm goes off and lights flash. This is embarrassing, at the least, to drive at night, so presently I have just parked it in the garage until I can solve it. I tried the driver door key lock/unlock - no difference. After setting over a week in my garage to dry out completely - no difference. I live in rural N.W. Indiana and there is really no need for the burglar alarm.

1983 240D Throttle linkage problems

file:///C:/Users/Norman%20Sumner/DSCN4878.JPG
Kent,
Do you know if these grommet/spacer can be replaced or do I have to fabricate something to fix whatever they are called. In case the picture does not work. The items I want to replace are part of the throttle linkage. The linkage comes straight from the firewall to a forked plate. The forks go through two slots, and the grommets keep the forks aligned. I was wondering why I had so much movement in my peddle before I received any response for the engine.
Any help would be greatly appreciated.
Thanks again,

1985 300D starter problem?

My 1985 300D starter seems to momentarily stay engaged on the first start of the day. Very short grinding noise after the key is released as if the gears are not disengaging on the starter. Rest of the day seems to be fine,only hear this noise if car has sat several hours or overnight. Looked thru questions on this forum and could not find anything similar. Vacuum related? I just started the self-mechanic routine, so thanks for any input.

'82 240D early shifting vacuum modulator adjustment ??

my 1982 240D auto transmission is upshifting way too early - I'm in 4th by the time the car is at 25mph. How much can I adjust the vacuum modulator to adjust this shifting? I recently replaced the VM because the car wasn't shifting at all higher than 2nd gear. The VM replacement fixed that, but now it's shifting way too early. i installed the VM as is out of the box. i know you can turn the key clockwise or counterclockwise, but i can't find any info anywhere about how much or how little. is there a spec that i should be shooting for on this?
