Default 16' trailer suspension maintenance

Noticed the trailer was not pulling real straight behind the truck last time I used it. So today jacked it up in the back and took off the wheels to get a good look at the suspension. Noticed some play in the shackles. Expected that the plastic bushings are worn out.

They were worn some so got new nylon bushings and new bolts with grease zerks. Side plates were not egg shaped so they will be reused. Old bolts did not have grease zerks.

Got one side done this afternoon. The other side tomorrow morning. Then do some measurements to assure the axles are square to the hitch ball.

On the trailer I am redoing the owner picked up the bolts with grease zerks, but got bronze bushings instead of the plastic ones.

Yup. Bronze with grease. Far as I know, you don't grease nylon bushings. I believe it can attack the plastic. Might be some nylon compatible grease available

Here ya go. You can grease that, but with care in selecting the lube.

Or just go the best way. Dexter makes bronze bushing kits with greasable bolts.

Found the cause of the dog tracking. The other side had egg shaped holes for the side plates. So picked up a complete set to do both sides. Now have to go back to the first side and replace the old side plates.

Good thing it is 65F outside, so nice weather for this job.

Next time out I will check on the bronze bushings.

I did get a little lucky today. I had two bolts with grease zerks that would not take grease. Initially thought I would just replace the grease zerk but found that were pressed in not threaded. I already had two extras from the four 4 packs I bought. Took the the two loose ones back and he gave me a new 4 pack. So at $17.25 for a 4 pack, I now have 4 extra bolts for a future use.

Just imagine how much money they save by omitting the threading process Big bucks over thousands of units. Bastards.
