My brother's partner has an r172 SLK 250 CDi.

A Halfords safety inspection (don't ask) has reported that os and ns front wheel bearings need adjusting and are, er, adjustable :dk:.

Any thoughts please?
 
I believe they are tapered roller bearings with a pinch ring for locking after adjustment….needs an allen key to loosen/ tighten. There is likely info out there as to accepted float but you/he can check their findings by lifting each wheel in turn and rocking the wheel in/out making sure you rotate it whilst doing so.
 
Easy job.
Cap off, loosen the allen key. Ignore end-float. Nip up with your fingers, tighten allen etc.

If your were being diligent, re-packing with new grease is worthwhile.
