89 r32 gts4 rear wheel bearings

[LINK17]

Hello All,

Ad per above my LH rear wheel bearing is noisy after driving on the highway. My mechanic said he would replace it so long as I have the bearing. 

My drama is I'm not sure whether it's a gtst or gtr bearing? And are they interchangeable because the gtst version is cheaper and I'm only running 200kW through the rear wheels?

Dude it's pretty easy to search that. Not the same as gtst. Gts4 means GTR bearing for the 4WDs as well as the 300zx and genuine is about $230 per side. There is an alternative with the GSP ones from Kudos at $165 each, and that also actually comes with the hub. I'm ordering a pair this week.
