Hi - anyone know the measurements for the 928s4 upper front ball joint rubber boots - I'm trying to source replacements in the uk
the Audi parts 431 407 377 A seem to be obsolete !

cheers

thanks - not so easy to source either - anyone know the big and little hole diameters - I'm sure I can find one to match !

cheers

I recently changed one of the upper ball boots on the blue car, a 1987 S4 Strosek. The hole diameters of the 928 boot I can measure as 15/34mm. The BMW boot is slightly smaller and fits better.
Any BMW dealer can get them for you or you can order on Ebay or from Hubauer in Germany. The low price boots from Hubauer come without the retainer clips. The 928 clips can be used.

I bought a set of different dimensions. Selected the biggest ones. But I heard that a VW van may have the right size
