Yes, in most cases a bearing puller or hub tool listed for a VW T5 will also work on a T6 because the rear
Wheel bearing and hub assembly design stayed basically the same between the two generations, especially for the standard Transporter and Caravelle models, so the puller dimensions and bearing fitment are unchanged. Just double-check the specs to be sure the puller is sized for your 2018 T6’s bearing outer diameter (usually around 85–90 mm depending on variant) and that it supports pressing the new bearings back in evenly; if you’re uncertain, look up the
TBS bearing part number for your T6 and confirm the puller’s compatibility listing against it so you don’t end up with a puller that won’t seat the bearings squarely.
