Hi
Please tell me whether there is a difference between the front suspension lower wishbone and vehicles without esp or active suspension.
Much obliged

If you're talking about the 99+ vehicles that got the larger brakes, there was a modification to lower.comttol.arm where the ball joints were no longer independent parts but instead part of the assembly.

Thank you very much. I'm concerned about the difference between the two bushes on my 93 SL R129's lower front wishbone and the ones on the replacement. Everything fits well and I haven't had any problems, but I would want some clarification on this matter.
Much obliged.

After 33 years, it's impossible to say what was accomplished. To make sure the bushing part numbers are same, it's recommended to check EPC through a few sources.

It is likely accurate if you obtained a lower wishbone kit. Verify that it is for the correct lower control arm, though. For the last few years, they altered, as I said before.

The later arms with the permanent joints are compatible with the older vehicles, but the other way around, the disc clearance is either extremely tight or nonexistent, so it's safe to say that they're backwards compatible.

This is the most comprehensive explanation I have been able to find after searching for part numbers, thus I'm really grateful.
