I have an 88 Westy with about 150,000 miles on her and when I go over bumps
such as speed humps, I can hear squeaking and groaning sounds.  I assume
that they are from the age of the rubber components that abound in the front
suspension.  Is there any sort of lubricant that might give me some short
term quieting relief?

I just replaced the passenger side upper ball joint but other than that,
It's all original as far as I know.

Thanks,
