Product review (4 stars): Used on Whirlpool LSB6400LW1 Washer - Fixed loud squeaking on agitation
The clutch, spring, and disc/drum were good and fit - but the anti-rattle clip (white nylon clip) did not fit or clip in to the drum.  Also the brake cam (large nylon plastic offset piece) did not fit, it was too tall compared to the original by about a half inch.  I reused both of these pieces with no issues.

I was experiencing a loud squeak squeak squeak on agitation cycle.  I disassembled to discover the clutch was glazed and overheated.  Replaced the disc and clutch lining.  Washer is now quiet and no more squeaking!
