At what mileage have you found you needed to replace the bushing? I have 78,000 miles on my 95 FD. I have replaced the trailing arms and toe links about 6 years ago with M2's upgrade, and upgraded the diff bushings 3 years ago. Thanks much...

 

I have about 64k on the chasis and just replaced the pillowball bushings, toe links, and trailing arms.

 

Don't replace what isn't broken IMO.
