IRS Diff
I recently replaced the front diff to IRS Aluminum outdrives diff. Now the gear mesh don't seem to mesh. I could feel that there is more fraction between the big diff gear and the little drive gear. I placed a shim as per manual on the long side of the outdrive and try placing one the other side. Problem still exist. Next, I placed 2 shims on the long side thus forcing the diff gear to move to the left. This increased the pressure on the diff bearing. Then I proceeded to removed the shims in the drive gear so it will be positioned farther back. No luck!!!
I switched to the aluminum because the plastic outdrives kept breaking with the slightest hits. I have tried the the steel outdrives and it works fine, but I'm trying to maxmium weight reduction specially with rotating mass.
I currently running the new tires from Medial Pro 25 shore and it is the best tires I have use on non spray/prep parking lot surface. Definitly well worth the $13/pr.
