    There has been discussion that using spring liner along the length of every leaf, as was done on most classic Corvettes, definitely affects the spring rate. It dramatically decreases the friction in the leaf pack, making it softer and progress through it's travel quicker.

    Oh yeah. That too. I'll be interested to see the results.

    I definitely don't need any more height so I'll be sticking with a short section on the unprotected leaves.

    I'm looking forward to reading your post after install & putting some miles on with the "fix" applyed.

    Mine have been bothering me for a while now and I'm not wanting to take my leaf packs off to fix it. I may just try the Zip Tie method.

    I posted about those liners a while back, glad someone's trying them.

    I'd be afraid to use adhesive though. Wouldn't want to attract any dirt. I think the center pin, leaf clamps, and the liner's channels will be enough to keep them located.

    My only reservation of going with those is the thickness. I feel they're still going to wear out like OZ's fix. Now I'm leaning towards drilling holes and installing conventional pads as a longer lasting fix.

    I agree. If you were to install the liner the entire length of the spring as it was designed, then yes, you would not need adhesive. The center pin would hold it in. Im only cutting short sections and installing at the tip. I'm using 3M trim adhesive which is designed for outdoor/ automotive use. Once it has bonded, it is no longer tacky.

    I just finished and was about to post pics... stand by...

    All done.

    Step one: Unload the rear suspension by jacking it up, placing jack stands under the frame rails, and then letting the axle droop.
    Step two: Jam a nice flat pry-bar in between the leaves.
    Step three: I cleaned in between the leaves with brake parts cleaner and a rag (mostly so the adhesive I'm using would bond nicely)
    Step four: I cut short sections of the liner, sprayed 3M adhesive on the bottom side, and placed them at the tips of each unprotected leaf.
    Step five: Finish your morning coffee that is now cold and then crack an almost-noon-beer



    Also... I used less than 3 feet of this stuff. If anyone else would like some, I'd be happy to cut off what you need, stick it in an envelope and send it out for a couple bucks. It'll save you the cost of buying the whole roll and maybe I'll recoup some of my cost of buying a whole roll. Let me know!

    A quick spin around my block and going up and down my driveway (which usually causes the noise) revealed a much more silent ride. For some reason, I have a creaking noise coming from my front end as well... but the rear is nice and quiet.

    That looks nice and clean. When my zip ties wear out I might take some of that off your hands.

    I agree. It looks good and performs well so far. I'll keep you all updated on how it wears and whether or not it stays in place. Just let me know whenever you want some!

    enough to go over stuff
    Its been almost two years and my dakars have been quiet for the last 12 months. The key to getting ride of the squeak is to flex out your leaf pack to the limit and get lots of dirt and mud in between the leafs. then it will be quiet.

    Good attempt. I'm quite skeptical about any adhesive working on the leaf springs. Prior to the zip ties, I tried the 3M multi-surface spray adhesive and the EPDM liner stuff, it didn't last 60 minutes off road before the leaf pack chewed it up and spit it back out.

    Im no stranger to the trail. I spend almost every day-off in the mountains of CO doing something. If it doesn't hold up, I'll let everyone know fairly quickly.

    Just got back from a three day trip traveling over Taylor Pass and then Pearl Pass... from Gunnison CO to Crested Butte CO with Aspen in the middle. The passes are quite gnarly this time of year and there was no shortage of suspension flexing. Out of the 8 sections of liner I installed, 1 of them managed to migrate 1/4". The other 7 didn't budge. I'm actually quite impressed.
