[diesel_mercedes] 1987 300 TD wagon for sale

 

I've decided to rid myself of my 1987 300TD wagon. I'm getting too old
and have lost interest in restoration. I've already done a lot of
repairs but the blue interior still has to be done and it needs a new
resonator and maybe some engine work. I just had a new starter
installed and a new water pump. Tires have about 2000 miles on them,
I'd guess. Has been garaged since I got it in 1997. Has new rear wheel
bearings. Climate system is defunct. Becker radio that works. Never
wrecked. One or two small rust spots near the right rear window and
radio antenna and I mean small. White paint is so so. Driver's side
door lock needs replacing. I'm located in Point Richmond, (Richmond,
CA) near the end of the Richmond Bridge to Marin.

I'm open to reasonable offers which are over what the junk yard will
give me. I'll be getting a trade in offer next Saturday but I doubt I'd
get more than scrap value since no one knows these cars very well.

That's it ! .

Now imagine it painted like a circus clown .

I might have seen the film @ The Classic Center , they always have some loop playing of old promotional films .

I couldn't find that video, but here's a good photo of the Mercedes swing axle (for some reason, it's upside down...):

While I was looking around the internet, I found this heartbreaker, supposedly caused by this rear axle system (though the Gullwing's version had two pivot points along the axle housing instead of just one):

The problem was that with the more powerful cars, the inside wheel tended to jack up when accelerating out of a corner, ultimately causing the rear of the car to break loose and fly out.  This became evident when MB began to drop V8s into the W108/109, especially the 300SEL with the mighty 6.3 from the 600 limo/pullman.

Thanx Mark ! .

I know *exactly* what you're talking about having watched an old Mercedes sales film where they painted the various parts bright primary color then drove it over some really weird undulating pavements with a camera hung under the trunk showing how it all moved .

Well, there's NO torque tube nor DeDion rear axle.  It's the old Mercedes "Swing Axle" that uses an exposed drive line from the transmission to the ring and pinion assembly.  It has a u-joint in the middle and a center, carrier bearing, and is not much different than what the w114/115 and later cars used (from about 1968 on).  The real difference is that instead of a the ring and pinion assembly being mounted on the frame, with two cv-style axles going out to the wheels, this old system has the ring and pinion attached to a mount that pivots at the frame, and a second pivot that splits the otherwise solid rear axle housing into two.  The axle that's inside of the housing side that's not mounted with the ring and pinion has a constant velocity joint.  This allows for "independent rear suspension", sort of.  There's a hefty coil spring that tries to push the two axle housings away from each other.  (On the higher priced cars, the w108, w111/112 and SLs, this spring was replaced by a hydro elastic damper which would compensate for loads to keep the car level.  Elegant in it's simplicity, and an advantage over the later, fully independent rear axle system, but that hydro elastic unit is big $$$$$ to replace!)  It's a lot easier to explain using pictures rather than words alone.

The upshot is that the axle bearings are not that much different to replace than on any old American car or light truck with a live, solid rear axle.  The two axles are pulled using a slide hammer, the old bearings are pushed (or cut) off, and the new bearings are pressed on.

Hi Dexter ;

First , you must put the chassis designation in the header box _every_time_ so those who just skim , but know , will stop and read , maybe be able to offer help .

Next : which particular bearing is bad ? there's a bunch in there , if just a wheel bearing I suggest replacing both and the attendand oil seals .

If a pinion or ring gear bearing , I suggest getting another entire used rear end , re sealing it and then install , drive way happy .

Torque Tube final drives are very sturdy and long lived . if it's failing , one needs to know why before doing more than wheel bearing service to it .

I hope this helps you to proceed .

My 67 Mercedes 200d has bad rear bearings. The rear axle is honestly weird and I'm not confident enough to tear in yet. From what I can tell it has a torque tube and design based on a De Dion axle. Does anyone have any experience with these?
