So the rubber bushing on my rear MAF control arms are literally falling apart. I have been getting a real bad driveline clunk on acceleration and deceleration and found out the MAF upper and lower bushings outback are junk. The entire axle is rotating back and forth in the bushings. They have about 15k on them and look like they have over 300k. I called MAF and they knew nothing. These arms were sold up to 2016 and then the company was sold. The new guys know nothing about the older style arms. They no longer sell arms and the recent ones they sold have poly bushings. Here are the questions they could not answer. Can I swap in OEM bushings into the old style MAF rear control arms? If not, are there any poly bushings out there that will work with my current control arms? The uppers have heims on one end that look good and are nice and tight. The other end is the rubber bushing that looks like old dry crumbly bread. The lower arms are rubber bushings on both ends and they are in equally bad shape. Any advice would be appreciated.
