I've just had mine apart on my 2018 TS due to a slight speed wobble... They were a nad too tight from the factory so thought I'd regrease while I was at it.
Plenty of grease in there (8.5k miles) but did em anyway...
Can tell you they are DEFINITELY not taper rollers and are the standard ball & Cup type
Torqued back up as per factory spec and all perfect now 👍
