Re: [diesel_mercedes] Sagging Rear End

 

Bobby,

I know that.  When I bought my 300SD, it looked like it had been lowered it sat so low, but since I'd seen this problem before, I bought it a new set of Bilstiens, and it went right back up where it belonged.  In fact, it went up so far it topped out the suspension, was several weeks before it settled down where it belongs.

Gas shocks have their own spring rate, and it adds to the spring rate of the springs, if they loose pressure, the car gets lower and softer, usually asymmetrically..

BK,
 
There are air shocks that help lift the car.
 
Gas shocks are pressurized, but merely to reduce foaming of the hydraulic fluid.  They are usually higher quality than the non-gas shocks in a manufacturer line.  So, if they lose pressure, they may not be as good a shock, but would not cause that corner to below.
 
I think.

I think it may depend on what kind of shocks are fitted.  Gas shocks that lose pressure at one corner will do what you describe.

Weak spring .These cars have the weakest springs,they need a muscle car spring to replace.

With Spring trying to make an appearance here in the Heartland, the wife has been 'encouraging' me to pull her 1980 300D out of winter storage.   So this past weekend, I open the garage door and notice the right rear is a little low.  My first thought was a low tire, which there was, but even when all tire are properly inflated the passenger side rear is one-half inch lower than the driver side.  Now that doesn't sound like much, but it is quite noticeable.  A peek under the car didn't reveal any obvious problems.  Does this sound like a weak shock or spring?

Re: [diesel_mercedes] Re: A little gas in the tank, also ultra low sulfur fuels

 

Lost,
 
\Is there an inexpensive way to get just the mineral oil?
 
Is the mineral oil in the drugstore the same thing?  Is it OK for fuel additive use?

Copied from another forum,

1. ATF (any flavor) is red in color. It also turns your fuel red. It would be hard to explain red fuel if you ever get dipped.

2. ATF also has friction modifiers in it meant for clutch paks in trannies, not in injection pumps with tight tolerances.

3. This kinda falls under "right tool for the right job". There are much better and cheaper additives to put in the tank designed for diesel engines.

And number 4. This is a quote from another forum. The guy that posted this works in the petrochem industry.

I don't think I would want to purposely run that much sulphur thru my engine as it will end up as sulphuric acid in the oil. And that much zinc run thru the injectors has got to eventually cause some erosion. So, lets look at Fords Type F ATF. It is a 20w mineral fluid with 12,000-13,000 ppm's of phosphorus, 3500 ppm's zinc, and about 800 ppm's barium. I can't believe this wouldn't poison a diesel engine. The acid load on the oil has to be tremendous. I would suggest using an additive that is made to do the job if you are using an additive at all.
