Any good leaf spring bushings?

I put 1" upcountry springs on my Jeep about 1 year ago from Quadratec. I used leaf spring bushings from Quadratec as well. This Jeep sees 99% pavement, with a little towing.

After 1 year I started hearing a creak from the passenger side leaf spring. The bushings are already shot. Does anyone make decent leaf spring bushings?

Re: Any good leaf spring bushings?

If the upcountry springs have the stock size spring-eyes, use the factory/OEM bushings. They're made with a higher durometer rubber then most aftermarket bushings and last longer.

If they're not stock size, see if they're YJ Wrangler size.( it's a common change spring manufacturers use to save money) If so use OEM YJ bushings.

Don't use polyurethane anything.

Go with Clevite bushings. MOOG and O'Reilly's Master Pro are often Clevite.

Skip the Chinese stuff.

Good to know you can still source the Mopar ones. I'll try to hunt some down.

One year old factory bushings on OME leafs. I'm trying to figure out how this happened.

Damn. Wonder if they switched suppliers to China.

No poly?
Weird?
I've had my polys in for about 9 years. As long as I keep em greased up they're quiet and long lasting.

Re: Any good leaf spring bushings?

Make sure you do the final torque while the jeep is on the ground and the suspension is at relaxed stance. When you torque it down you're actually locking the center sleeve into place, which lets the outer part move by stretching the rubber and returning to rest. If you torque it in the air, the rubber will always be under load and won't last very long.

Agreed. I've got poly bushings in my shocks and leaves. Granted, I haven't had them in for 9 years, but no complaints so far.

Very important. Mine was torqued on the ground, so I'm still trying to figure out it's issues. I'm going with factory again so we'll see if I was just a fluke.

Chrysler is sourcing some factory parts from China. Why not use the Clevite bushings? Your dealer bushings should be under warranty so check into that and get them to replace them for free.

Re: Any good leaf spring bushings?

Yes, Clevite would be best but how do you identify these? It appears Tenneco purchased Clevite but this does not offer us much in the way of useful information.

I think there are two factors with these bushings:

1 - Quality of the elastomer.

2 - Thickness of the metal surrounding the bushing.

Yes, urethane will last a long time but is usually regarded as being too hard for leaf spring bushings on the Xj. Control arm bushings and sway bars are the applications for urethane.

I do not know how we can ensure we purchase good parts without seeing them in our hand. I need a set of new bushings, have a set of poor quality ones here at the house so I would appreciate any information regarding good choices to pursue.

If it's Clevite it will have CLEVITE letters marked into the bushing material - should be easily identified by opening the box at the store.

Re: Any good leaf spring bushings?

I use Clevite as the generic term for any rubber bushing with inner and outer steel sleeves
