ORD Bushing Swap....Getting more difficult now!

    OK....I jinxed myself by talking too soon about how easily the greaseable front bushings all went in! [​IMG]

    Still invigorated by my success, I decided to tackle the rear spring mounts next (not the ones in the shackle, the front one) Well I got the old bushing out....there's an inner metal sleeve, a rubber bushing, and also an OUTER metal sleeve that were all removed in preparation for the swap.

    The problem is that the spring eye is NOT round! When I put the new bushing up to the hole it's obvious that the hole is slightly oval-shaped and the new bushing is not going to slip right in. I tried clearancing the hole slightly with a small grinding wheel, and I got it slightly 'rounder' but the fit was still VERY tight. I could see that the new bushings were deforming, and the metal sleeve seemed to really be pinched.

    Since this bushing has slots cut for the grease to flow through it, I am concerned that being FORCED into the springeye is going to prevent the grease from really flowing everywhere it needs to. I am considering re-doing these bushings....but I need to know if there is a tool that can "hone" that spring-eye to a perfectly round shape? Am I just being too paranoid....will these bushings work fine even though the fit was so tight? The bushings were not chewed up at all, just a lot tighter fit than the ones in the front spring packs & shackle....

    Any ideas?

    You should be fine, there's a pretty wide tolerance range in the fit of the urethane, but if you're concerned, you could easily egg the bushing itself. That may be the easy way to do it. Keep in mind you're going to have several hundred pounds moving this stuff around, so a little extra rotational force isn't going to mess with you much. It's hard to say how tight is too tight, but if you can't tap the sleeve in with a rubber hammer and reasonable force, clearance the bushing.

    Thanks Steve!

    I am so physched about how well the "small" changes you suggested are already helping! [​IMG]

    Any idea about when those rear shackle-flips will be ready to ship?

    I'm off to Hollister Hills to meet up with a few other CK5'ers and try out my new "goodies"!

    Thanks Again!

    Won't know where we're at for couple days here, I have to get home first. Best guess, they'll leave the end of the week sometime.
