A few tips:
People say to buy the W124 lower control arm bushings (at pivot point on K-frame), since more robust for the same price. Read the post "red-neck ball joint removal". As you found, it isn't hard to beat the lower ball joint out with a big hammer. Pressing the new one in is much trickier. I found that the new ball joint was slightly larger diameter than the original, which made it even tougher. I used the Autozone rental C-clamp press, though later bought HF's on sale for next time. I vaguely recall I had to use another shell to those in the kit to fit my spindle. I hang onto large ball bearing races and such for similar press adapters. It seemed the C-clamp was going to break. Despite its thickness, I could see it bend appreciably. I heated the spindle's hole w/ a propane torch, which seemed to help. Later, I read Rollguy's tip to tighten the thread, then tap the end of the screw w/ a hammer (other end on concrete floor) to persuade the ball joint into the hole, and repeat. I will both heat and tap next time. A little oil might help, but I wouldn't use grease. There is an adapter (ebay, $$) which lets you use a hydraulic shop press. It is basically a tube w/ a cut-out to pass the spindle's arm thru. But, I am OK w/ the C-clamp press. I tossed the thin boots that came w/ the new ball joints and used polyurethane boots from Energy Suspension (extras I had), which you can buy from ebay or speed shops.

Also, where can I source torsion bar bushings? I don't see them listed here on peach parts.

Pelican has them here in the store. It'll be called the eccentric bolt repair kit, I believe.

Perhaps you mean "sway bar" (more properly "anti-sway"), since it does work by twisting the rod. I bought 2 pairs recently for my W123's, just to have on hand next time I am in that deep (battery tray and/or brake booster off). I bought cheap on efay, but P-P must list.
Re "torsion bar", my 1960's Mopars have them (instead of coil springs). Porsche used them, as do some recent U.S. trucks. Advantages are they keep suspension weight down low and you can adjust ride height by turning a bolt.

Taking a quick afternoon break. Lower ball joint on the passenger side is now pressed in with the Autozone press, my electric impact gun, and a homemade adapter to go between the Autozone press and the ball joint flange. Now to replace the lower control arm bushings and guide rod to control arm mount, and then I can start reassembling the passenger side. I should have at least that much done this weekend.

One should consult the pictures in the Chassis Manual .... as the scuffing which would not be correct on other cars may be considered correct on our MB's...
Everything goes back to the Factory Shop manuals....

The repair work I did got the car to around 95% perfect. It feels stable and solid on the road again. I'm finally really enjoying driving it. But, I still have an intermittent clunk when coming to a stop. I figured the problem was the one part I avoided replacing - the sway bar to firewall bushings. I replaced them this evening after work. It wasn't as bad a job as I feared. I did the driver side bushing first. Most of the time involved was taken up unbolting the brake booster. I ended up simply unbolting the booster, but not disconnecting the master cylinder. That worked fine and I had just enough clearance at that point to replace the bushing on that side. The passenger side bushing was easy. I did both with the wheels on the ground. I only made one mistake. When I bolted the booster back in, the booster pushrod didn't seat properly with the brake pedal. I didn't think to check it until it came time to reconnect the pedal to the booster. Unfortunately, it's late now, so this will have to wait until tomorrow evening. I wasn't planning on driving the 240D tomorrow, anyway. When I get home from work tomorrow, I'll unbolt the booster again and seat it properly with the brake pedal. Then, I'll test drive it. The sway bar to firewall bushings are literally the only suspension part I hadn't yet replaced on the car. I'm pretty confident this will fix the clunk once and for all. |

I thought I posted this, but I guess not. I finished the car a while back, and have now posted my front suspension DIY video:

W123 sway bar to firewall bushings
I've changed these and removing the brake booster and battery try isn't at all necessary .
Just look over and think the job through, I used some long, 3/8" drive wobble extensions, if you have the control arms off for ball joints the job is *much* easier . Took me about three hours just for those two firewall to anti sway bar bushings . They're *very* important but no one ever wants to do them .
