So I installed a fresh set of Dunlops on the rear end yesterday and it did wonders for quieting down the rear end. There is still a bit of bearing noise, however. At 140k I think that is to be expected. I can load the left side (turn hard right) and silence the sound, so it's the right bearing that is bad. I've searched and found a few threads started about bearing replacement, but haven't found anyone here that has actually DIY'd it. Anyone done theirs yet?
