i had 2 gallons on my mbx6 and decided to replace all the bearings. left rear inner and inner clutch bearing were gritty. all the others felt great and have been relegated to the backup bearing drawer. i spent a little bit of xtra time setting up my diffs and installed brake caliper springs and driveline feels very free. the mugen bearings did very well for me.
