I have just finished changing out the bushings on my '05 Suites--not an easy job for an old man, but got it done. Just have to try it out...
The bushings come as a set with either 8/12/14 or 20--or some numbers like that. They are also available from Titan industries.
I have previously worn out the original plastic bushings (waited way too long to check them) and then brass bushings after 20 months + wet bolts. This time I put the NeverFail bushings in with the wet bolts, figuring not to grease them.
There are 2 ways to do this--bushings only, and bushings/shackles/bolts. Depends on what you find when you tear everything apart. Having watched some UTube/Lippert videos, they don't come close to the difficulty faced with 8k axles and 17000lb trailer weight. If I have to do this again, will take it to a spring/axle shop and have it done by experts. Granted, tho, I don't have the strength I used to have, nor patience--but it is done, just have to tow to see if anything falls off...
So far, NevRLube bearings from Dexter have worked well, hope the bushings do also.
