I'll weigh in with my experiences here, since I had both squeaking an knocking.
Replacing the UCBs fixed my squeaking, and has stayed that way for about 4-5 years
now, with plenty of rough road travel. Strangely, only the pass side had the proble, so I
left the driver side alone.
The knocking was caused by installing KYB shocks and using the bushings supplied
with them. Fortunately, I had kept the stock bushings, and on the advice of the list, put
them back in - no more knocking! This is on an '88 Westy, now with 382k kms.
