Definitely easier than a tub-spider for a front load washer.
The supports for the upper rack that fit into the slides/rails had failed. Of the four supports, the 2 rear were okay.
Rust underlying the coating made 1 fixture difficult to remove, but just need a little persuasion.
Lower rack rollers are just snap in. Old and tired, they were popping off too easily. New ones, 6, make it nice. Probably could have only replaced the front four.
