Front end shakes and rattles

I have a 1983, 300SD. At speeds around 60 to 70 mph I get vibration that fells like it is coming from the right front wheel and I also feel it thruogh the gas pedal. Also when making a right banking turn, (as in going from one freeway to another freeway), the front end will shake violently. This also feels like it is at the right front wheel. Can you give me any help as to what to look at and what to look for?

Overheated rear brakes

I drove 15 mi to work, via high way, with e brake partially on. When I got there, the wheel was smoking. I pour gallons of water on them and let it cool down and drove again for about 10 mi. Now I found the brake didn't seems to returned after it's applied, the rear wheels would be almost fully locked after no more than 10 times of braking. The more the brake is applied, the the shallower the pedal gets. So I towed the car back home. What could the heat do to have caused my rear brake to stuck whenever it's applied?

timing gear breaks on 420 sel

Hi I am brand new to the forum. My name is Lewis in Nor Cal, I have owned a 1990 420 sel for 3400 miles now. IT has 200120 miles on it, 1 owner and is in perfect shape. Just did new rotors all around belts and oil change. I went to start it on 09/15 and I heard a big bang. opened the hood and found something had made a 2/3" hole in the drivers side vale cover right on top of the timming chain. the motor did not start during this time and has not since. I am going to do a compression check to see if any valves hit pistons etc.

'83 240D Power Steering "Slop"

I've got a '83 240D with Power Steering. Riding down the highway, the steering has quit a bit of play. I'd estimate I can turn the wheel about an inch (5-10 degrees) without any noticeable effect on the wheels. With the car parked and off, if I grab the input shaft to the steering gear box I can turn is about 5-10 degrees before I see any noticeable movement underneath at the control arm. SO I believe most of the "slop" I am experiencing is coming from the gear box and not further down (tie-rods, bushings, etc.). I noticed in the shop manual that there is an adjustment procedure for the gear box. It looks simple enough but shows torque curves through the steering handle travel.

Puddle of diesel under 74' 240d

So lately Ive been noticing a small puddle of diesel under my 240 when it has been parked for an extended period of time. I haven't worked recently and am noticing that puddle getting bigger every day. Where could it be leaking diesel fuel??? Near the injecter pump or is it a cracked fuel line or what? Also, I do know that the engine in the vehicle is not original and that it was recently replaced so could this be the problem any help would be absolutely fantastic. Thanks!

Better ride for 83 380 SL

Hi, My 83 380 SL does not ride well. I replaced the shocks and it seems like it needs a whole lot more as it thumps over rough roads.. What DIY things can I do make my car ride better? I read in this forum that replacing the front subframe bushing is an easy fix and greatly improves ride and steering. Any suggestions?

240D Starter Issues

I've got a 1977 240D with a starter that won't turn (or do much of anything) when the key is turned. It will, however, start right up when I bridge the two screw terminals on the smaller cylinder on the starter assembly (solenoid?). I'm not too clear how exactly the starter motor works, so I'm looking for some help on what to look at/for. More, possibly relevant, info: Drove about 150 miles through 100+ degree heat. When I stopped for lunch, car exhibited above symptoms. Banged on large starter cylinder, car started with minimal fuss. After sitting in a driveway overnight and most of the next day, starter wouldn't turn at all (or even "click"). My friend suggested bridging the two screw terminals on the solenoid with a screw driver, and this started the engine right up.
