clunkity, clunk, clunk

Hi all,

73 roundy...slowly working my way through the car, improving where I can.

I have a mysterious clunk that I can't identify. Sounds like it is coming from the front suspension, possibly pass side. I've had the car up on stands replacing brakes and brake lines, etc. and crawled around looking for the issue...couldn't find anything.

Sound only appears over bumps, and I can't replicate by bouncing on the front while stationary. My initial thoughts were: engine mount, loose front suspension components, bad bushings, broken spring. I've checked all of these as best I can and don't see a thing wrong. Most bushings have been replaced with PU, shocks seem fine, engine mounts look OK.

Any ideas, I'm nearly stumped and about to take it in so someone on a lift (and more knowledge can check it out)

loose: wheel bearings, lug nuts, brake caliper/bolt, steering box retaining bolts, battery. Worn: tie rod, drag link and steering linkage?

...wheel bearings, caliper bolts, and lug nuts I've checked and rechecked. The strut bearings and top nut are worth me looking at. I've never touched them, and am not familiar with them. The driver and pass sides look slightly different though, and I can see bearings, which doesn't seem right.

area of this site, "Suspension Rehab" then scroll about 1/3 of the way down until you see a drawing of the sequence of spacers, washers, etc.

They MUST be complete and in this order or you will hear clunkity, clunk, clunk when you go over a bump.

You can not replicate this sound unless you go over a bump. You can see the sequence of washers and spacers unless you take it apart and look at it carefully.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
