Alternator Belt 'problem' ... 1984 300Turbodiesel...

Since I upgraded my glow plug relay to the type of relay that leaves the glow plugs on for a few minutes after start up, the alternator belts have been squeeling until the relay shuts off. I would like to put in a solonoid on the power supply to the relay with a momentary on button on the dash... But, in addition to that, I simply need to tighten the Alternator belts. It seems an easy thing to do on a car like this, which is so comfy to work on, but I can't seem to get the job done. It seems there should be a bolt, or a nut, to loosen behind somewhere, then turn the long, skinny hex shaped thing, and then tighten up the whatever. I can't find the bolt or nut, or whatever!

Small vacuum lines

I recently purchased a 79 300TD wagon. I have discovered many hidden problems with the car since I purchased the vehicle. The main one is the discovery of a 3" hole behind the battery and tray. It was hidden by a poor fiberglass patch job and the battery.This has been leaking into the car and sitting on the rear passenger floor boards. The floorboards are also rotting and hidden by rubber undercoat. Anyhow, when I bought the car I knew it needed a new heater servo and amplifier.

Suspension problem on '83 240D

So the other day I was out driving and started hearing a loud clicking noise whenever my '83 240D was in gear. I assumed it was the brakes since the rear brakes need to be done, but when I got out of the car and took a look I noticed that the rear right wheel was angled away from the body of the car. I jacked the right side up to get a better look at the suspension, but I know more about engines than I do suspensions and I really was just looking for something obvious that was broken.

Ellusive Transmission leak

Hello, I have been dealing with an ellusive tranny leak for about 7 months now. I purchaced the new gasket kit from you guys at MS, and everything went fine. Only I have a dilema. I get a steady drip, drip leak on the drivers side of the pan. WHat else besides the gasket could leak? Could the pan be tweeked, it looked straight, the tabs and all. One of the front ones were bent a little out. I think I straigtened it. If not do you sell new or good used pans? I am ordering the transmission hoses, for precautionary measures, or perhapps these hoses are leaking? I rarley look up under there, I only have a small area in the alley to work on her and the tranny seems to be the 'black hole' area. ANy help would be great.
