Didn't the driver hear it?
I replaced that on my previous truck.
The rattling noise it made ........and it wasn't worn half as much as what you posted.

 

With dump trucks in the fleet, I probably do 6-8 trucks a year on shackle pins and bushings. Never had a set even close to that bad. It was a big investment, but I have the tiger tool for pulling the bushings on the truck. Real time saver. Also have adapter for low air leaf spring bushings and made adapter for Jost 5th wheel pins. Awesome, but pricey tool. It was easier to purchase when I was a bachelor!

 

When Paccar started putting those stupid rubber bushings in the front springs we converted quite a few back to the threaded greasable style. Big, long ### drift with an old threaded pin welded to the end. 20 lb sledge. BANG BANG BANG!

 

I'm still not won over yet. Yes it is miles ahead of what it used to be, I'm just not ready to accept so many errors that have been present for too #### long already. It seems like in 2030 we might have a decent full functioning program.

They only make noise if the side shackles are loose and they slap in comers. Honestly as long as the weight pushes down it shouldn't make noise unless the driver catches some air on a pothole or drives off road.

 

I actually prefer the rubber bushings to the greasable style. No grease to rub your leg on. No people to argue with during safetys as they have a "small" amount of play. They come out easy with a torch and in gentle with a short 4lb hammer if you ram a prybar into curl of the spring to open it up. The tigertool setup is slick as well. I still think a torch might beat out the tigertool for speed if used by an experienced tech.

 

Problem we were seeing was they were pounding out in under a year on the logging trucks. The greasable threaded pins seemed to hold up better in that application.

 

Or a concrete road where the end off a slab is inch higher then the beginning off the next slab.
Multiply by X number off slabs.
Trust me,you will hear it.

 

I agree with you on slow to fix issues. Seems like for every fix they make, they create two more problems. Checked release notes on latest version and still can't run turbo functionality test on some EPA17's.
Rubber pins and bushings are ok for general over the road, but suck in vocational. When they wear they always chew up side bars and elongate the holes in them. I replace with steel sidebars regardless. I cut many the early ones out and I am somewhat a Charlie Daniels (RIP) of the smoke wrench, but I can't compete with how fast the Tiger tool is. Rarely have to pull the hangers it, except for ones with hanger behind battery box or AFT.

 

Just rolled in today. All 4 low air bushings are like this. Worst ones I have ever seen. Springs must be wandering around like crazy.

 

Newer truck? Seen Pete had info that spring bore tolerances out whack and were offering oversize bushings. I enjoy when they have those issues because then you get to see who really makes the part. Springs are Hendrickson.
