1985 300CD rear axle boot repair / interchange ??

I believe I'll have to order your can style axle drive shaft, Item: SRG-COMNRAS. After hearing a loud knocking noise, sounding like a loose U-joint, I discovered both boots torn on the left axle. No idea how long they've been this way. I cannot make the axle move to show looseness by hand and the knocking is not all the time while driving. The left axle is the can style. The right axle is the bolted spyder cover style. The boots are not torn through yet, but show cracking. Do you sell replacement boots for this style? I was not able to find this specifically on the web site.

87 300TD (6cyl.) & 85 300TD parts commonality question

Quick question...what engine/fuel supply parts are common between these two? Browsing through the catalog, looks like the injector crush washers are different, glow plugs are different, mail fuel filter different.

My main question...are the injector nozzles & injectors the same (but perhaps w/different pressures?)? If the injectors are different (visually, hardlines look smaller on OM603), are at least the nozzles the same?

'87 300TD Wagon, OM603 6 cyl, trap oxidizer removed
'85 300TD Sedan, 5 cyl, no trap oxidizer (federal version)

Aftermarket radio wiring

I have a 1980 300SD in which was installed an aftermarket (Blaupunkt) radio. The left front speaker is the only one which currently works. I have checked continuity on the other speakers: there appears to be none. I also receive only a couple of stations, suggesting the antenna connection to be poor. I suspect that all of these connections were violated when the previous owner had the car repainted. Where do the wires for the other three speakers run? what would be the easiest way to access the speaker and re-establish wiring to the radio chassis?
Thanks,
-Steve-

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.
