300D Replacement Axle Spacers

Do the replacement axles, the can style, include the spacers between them and the differential? I asked a while ago about having on spline stlye and one can style, and you said it probably wasn't harming too much. Now I have the money and would like to replace both axles, but to make the wrong (which I didnt know at the time) stlyle axle fit, I had to remove the spacer. I'm dead in the water if I remove the rear end and find out the axle doesn't fit due to a missing spacer.

Preventive maintenance, avoid catastrophic failure, '82 300D

Hi,

I purchased today an '82 300D Mercedes with 150k miles for $1500, but there are no maintenance records that came with the car.
The car is running fine, but because I have no history, I prefer to assume that none of the maintenance is up to date.
Beside the obvious fluid and filter changes, WHAT ELSE I NEED TO DO TO AVOID CATASTROPHIC ENGINE FAILURES?
Is it possible to get a list or point me to one if it is already answered?

Thanks, Mike

1984 300D front pipe replacement

Hi all, hope everyone is healthy and enjoying the new year. I am in the middle of replacing the front pipe on my 1984 300D Turbodiesel. This is the pipe that has some accordion flex incorporated into it and runs from the back of the turbo to the pipe of the resonator situated just under the passenger footwell. My question: Is the seal ring or "donut" the same type on both ends of this pipe secton?

Thanks for any help.

1984 300 D fuel reserve light.

Hi all. My fuel guage works with the exception of the "low fuel light". When I go to start the car the light shows so I know the bulb is good. It just does'nt light when the fuel gets low to the point where it should come on. Can I take the sending unit out of the tank and see if the contacts that would trigger the light are some how being impeded? Can I perhaps clean the contacts rather than spring for a new sending unit. I can live without the light but will try an easy cheap fix.
Thanks Mike G.

1984 300D Noisy Turbo

I have a strange noise that sounds like a fan with bad bearings. I hear it when the car is under load (going up hill) or just hard acceleration. Sounds to me like it is coming from the turbo. Is there any typical recomended areas to inspect that would cause this such as the EGR valve or intake manifold for this car. Also is there a cleaning solution that can be directly sprayed into the Turbo?
