Re: Got axle wrap. Traction bar or more leafs?

You should be able to find the article on there web site. There is a special made set of spring packs out there that are designed to eliminate axle wrap and JP tried to copy them with an old set of springs as a home built trick. The article said it worked out well for them. Because it's a normal spring that you are inserting and not an add-a-leaf, it shouldn't stiffen up the ride or cost you much flex.


'88 Sahara, 4.2, auto, 4.0 head swap (finally), no trac bars.

Re: Got axle wrap. Traction bar or more leafs?

I did the JP "recipe" using YJ springs cut down and added to OME spring packs SOA.

The ride was HORRIBLE! Super stiff.

I'm guessing it's because of the different spring rates of the stock YJ springs and the OME packs....

The ride wasn't just a litle stiff, it was really bad, and flex was NON-EXISTENT. Worse than it ever was SUA.

Since then, I've removed all of the extra leaves except the extra top leaf in the rear. I'm still deciding on an anti-wrap bar, and with my 4banger it seems to do OK.

BTW, this is on an 8.8 rear. Stitch weld the tubes to the centersection and it will be fine.

Charly, when you say to stitch weld the tubes where exactly do you mean it? Do you grind out the plug welds and do it over or just weld some short section of beeds around where the tube meets the housing?

Tibor-
Welding the tubes to the pumpkin is often done by placing approx 1" to 1.5" long beads into the seam. These 'stitches' are applied altenately at one side of the tube, then the opposite to help prevent warping.
This is almost a "must do" on CJ rear AMC 20's here in slick rock country where they can let go with a huge "BANG"! [img]/wwwthreads_images/icons/shocked.gif[/img] unless welded.
Four 'stitches' at the compass points seems to be a pretty common technique though I've seen it done using two 2" long beads, one fore and aft, leaving the top and bottom areas alone.

Re: Got axle wrap. Traction bar or more leafs?

Hey Jaffer, good idea! My brother is getting ready to weld the tubes on his '84CJ's 20. The 4 smaller welds should have/cause less stress & hold just as well(?). Isn't the pig beefed at these positions (don't remember)? I know the Dana centers have a spine on the top and bottom where the tubes meet.

Jaffer, I assume since the Ford 8.8 housing is nodular iron that a 7018 rod on my onboard welder would do the job. I don't trust the power of the 110v wirefeed I'm using would be enough. The tube wall is what, around 1/4" thick? Time to paddle the puddle. [img]/wwwthreads_images/icons/smile.gif[/img]

Re: Got axle wrap. Traction bar or more leafs?

Here's a picture of H8's solution, a ford radius atached to the axle(don't know how) and then to a bracket on the frame. He said that he leaves the nut very loose and it doesn't hinder flex. Don't feel bad Tibor...My spring under axle hops pretty bad if I get on it too hard.

5.0s and 4 speed = lots of broken parts!!!

Re: Got axle wrap. Traction bar or more leafs?

Very cool! It's mounted sideways so the tabs on the axle end are perpendicular. Probably creates a wee bit of offset. Very interesting _and_ CHEAP!

Re: Got axle wrap. Traction bar or more leafs?

Yeah, I saw that before. Course it's H8, he can make an air hose serve as a urinal if he wants to. [img]/wwwthreads_images/icons/wink.gif[/img] Anyway, for now I'm gonna stick with a proven design like a spring pack with 1" thick leafs on lift blocks.
