Thats funny. Where is he?

There have been a few times when I was calling around for these parts and the parts-guy would ask "front or rear?".... Did they mean the LCA?

Questions about this procedure - can you confirm that you left the calipers on the rotors? Where did you disconnect the park brake cables?
left the calipers on

park-brake cables disconnected at the lever-arm (actuator) where they meet with the main 'pull-cable' from the cabin. About mid-body near the driveshaft pillow block.

126 front and rear suspension is very similar to 123. The main difference is the guide rods attach to brackets that have two bushings each -

A crossmember spans the brackets for no seeming purpose than to splash fluid draining from the torque converter.

124 (and 201 and 140 and...) have a more independent rear subframe that attaches at 4 points. The diff attaches to the subframe, not directly to the chassis -

Fantastic pictures by the way jt20!

I especially like and approve of those nice chunky bits of wood - perfectly suited to this job. Well done.

Are you planning to do your own alignment? (I know you can't adjust anything on the back apart from ride height via the rubber "shims" or if you have those Gucci eccentric trailing arm bushings that fastlane sells but it would be nice to know if the rear wheels are straight in line with the front ones)

Ahh, that takes the kink out of my neck!

Is it an improvement for the newer models or just a change?

I've been watching this thread since it started.

It is very interesting, very helpful and a lot of fun.

Great job guys. http://www.peachparts.com/shopforum/...ons/icon14.gif

As always, thank you for informing. This is an excellent way to see how car design has developed over the years.




SJH: I like to leave the pictures all contorted for the viewer so you get the full experience of just how painful and agonizing it is to work on exposed aggregate (ask Charlie's knees.).

I defer to those who have blazed the trail. :bowrofl::bowrofl::bowrofl:

I've just spent some time under my 124 and was trying to visualize what was in your picture. Ultimately I cheated.

So I take it the newer design is an improvement. I think we can agree, even with the great daimler benz, the passage of time does not always lead to improvements.

Great thread.

I'll be doing this within a year so it helps.

If you appreciate more precise handling then it's an improvement -

I appreciate the softer ride of the 140. I don't know if that's a product of or facilitated by the 5-link architecture.

From experience, simple swing axles are dangerous, particularly a V8 W109 I don't know how 6.3s stay on anything less than a straight road. I got into some hairy situations with a 300SEL 3.5. Eugen Boehringer should have a driving school. I've never pushed a 116 so I don't know how surefooted it feels. A 126 rolls so much that I let up before the tires and suspension quit. A 140 is surprisingly nimble for its size and heft but I don't know if it's actually quicker around turns than a 126. A 124 blows away the heavyweights in turns :)

Every S-class I've driven I thought was spectacular and then I got in my E-class to go home and knew that I was in my car. I prefer a tighter suspension, quicker response, etc.

Maybe it goes back to my early days when I 'bonded' with my Austin Healy Sprite.

I've had my w124 ('90) for a year. I bought it 10 days before going into the hospital after saying goodbye to the w210. The seller, advertised here, stated it was completely maintained. Of course I've spent the year just starting to do what needs to be done.

There is quite a bit of 'lash' throughout the suspension. I think I've got most of it out of the drive train (motor mounts, transmission mounts, flex disks, carrier bearing and U-joint - remember seller stating car was completely maintained :rolleyes:) but I've not started on the suspension.

So I've not experienced a tight w124 and am wondering what it is suppose to be like.

In fact I'd say so far that my old w123 felt every bit as tight on the road as this w124 and in some ways was better.

I'm hopin' that with more work I'll find there are capabilities with this coach that I have yet to experience.

Is that the terminology to describe the subframe architecture for the w124 and later models?

Gawd, a 124 is like an anorexic tween on Ritalin compared to the "heavies". And the 300D takes the cake for crackhead like reflexes.

The 400E doesn't have that spring in the step that the 6's do, but it more than makes up for it with brute force.

Stuff a 5spd in there and it's even more fun :P

IMPROVEMENT IMPROVEMENT :shocked:

Everyone knows the 124 is like the Starship Enterprise compared to 123/126, which shares like everything, lol

I heard it called that in some marketing literature when the 201 was introduced.

I'm seen the term used here. I wasn't sure how it was applied. Thanks.
