I 'think' I feel something when I place my finger on the rod sticking up thru the upper mounting for the shock in the engine compartment. I can say with certainty though that it isn't coming from either control arm bushings, either inner or outers, upper or lower, nor the trailing arm or anything in that area - spelled RELIEF! Sound get's louder the closer I place my ear to the upper part of the fender well. That's not the final word, but the intermediate analysis thus far is that it's a click in the unloaded shocks.

I listened carefully following the sound and believe its under the shock cover (new bilstein shocks, properly installed with an MB W113 professional expert by my side while I did the work). The sound is coming from above the upper control arm or at the upper shock mounting area. at least approximately, and have eliminted some possibilities at the very least.
However, I was able to isolate where the sound is emminating from. While I cleaned joints off even more and spent effort to see if I could actually see any motion, I still can't see anything, so it's hidden inside something. I spent more time today trying to isolate where the sound "click" I hear when lifting or push/pulling up/down on the spindle. as I reflect with detail on the sound I hear when backing out of the driveway over the gutter while turning hard to or near the stops, you're absolutely right. The 107 and 116 front ends were even worse at this because the steering stop was on the lower controll arm and moved verticaly against the trunion stop when the car rolled over a bump with the steering held against the lock.Īl, thanks. The best soloution anyone ever came up was, "Don't do that and it won't make that sound". It has to do with the steering trunion being forced against the mechanical stop of the lower outer bushing and twisting against the lower controll arm to where it binds. The sound often described by customers as "crunching" when the steering was held hard against the end stops and rolling over a bump was a common complaint of Benz cars of this era.
The coincidence of sounds, both from the front end (backing out of driveway and up/down spindle "click" sound when push/pull on the spindle) suggests a probable common source and relationship between the two. sound's are similar.not a "thunk" but a "click" or high pitched "clunk". I don't and haven't had any noticable steering problems, but I have noticed a slight clunk or click in the front end when I back out of my driveway over the slight gutter with the wheels cranked over as I back into the street. Is there a definitive way to tell which parts have the play? while everything's still on the car? If not a definitive means, then what are the logical progressive (easiest to eliminate) choices in determining what's causing it. I can't see even a hint of movement anywhere - but I may not be looking at the right places either. some piece metal is 'hitting' another piece so something's got a clearance somewhere. I don't have a dial indicator handy so can't measure it yet, but what caught my attention first was the slight "click" sound. both? ,or is the play play in the king pin? If in the king pin is it purely a vertical play or would/could it be OD/ID clearance? This movement is very slight. if control arm bushing's I assume it's in the outers. So is this most likely in the control arm bushings. It's about the same sound and 'feel' on both right and left sides of the car, only in vertical axis (12 & 6 oclock push/pull). I know it isn't in the new bearings ('cause I repeated the sounds and 'feel' just pushing/pulling on the spindle end). There's no such sound when I push/pull at 3 & 9 oclock. front end of car's on jacks on the chassis near the tire jack holes. This is all with no load on the spindle by the way. though I can't see any movement even carefully looking with focused lighting at the ends of the king pins. final end play, when I noticed in push/pull (at 12 & 6 oclock) a slight click sound with a very slight feel of some up/down or back/forth tilt (can't tell whether it's pure up/down or tilt back/forth). Just got my new front wheel bearings installed and back on the spindle, torqued down to approx.
