    What diff bushing to go with?

    I think I've decided to go with OEM rubber for the two smaller bushings and poly for the main rear bushing. What to get? My #1 priority is durability since I don't want to have to do this again in 75k.

    ECST sells the purple powerflex bushing for about $50. How's that one?

    Majority of places sell them as a fill set of 3.

    I'm going to go with the akg units.

    Powerflex are bought as either the front diff bushings (pair) or rear diff bushing.

    I've heard conflicting reports. Some say they hear a little gear noise or vibration with poly diff bushings, others say they don't notice any difference in NVH at all.

    Yea I've heard their quality has vanished in the last year or two.

    Now who has the tool to remove the bushings from the subframe?

    I know I can get to them but got a feeling removing them from the subframe will be a pita.

    Yes. It will. Sockethead and I both agree there is no way without a special tool or removing the subframe itself. That thing is wedged in there and the sway bar hangar is RIGHT behind it blocking access.

    You were not able to replace your bushings when doing the diff install correct? I just placed an order for the AKG diff bushings.
