He might be talking about the hubbearings in the lower front arms on left and right side. Lower arm has a upper bearing and lower bearing and can get play, especially on the left side if car has hit a curb, or potholes alot on road (hub bearings do fail on GTR racecars after hitting curbs alot, so is a common problem and they replace the lower arm on GTR racecars). One of the reasons why I try to avoid potholes when driving.
If he is right, you'll need to buy the whole lower arm from Nissan, as I noticed Nissan dealer (the dealer I got parts from which was a authorised Skyline dealer) only sells it that way with lower bearing (due to car might have hit a curb and bent the lower arm). Upper bearing can be bought aftermarket.
I gather he means to raise car to get a correct alignment. He is correct, once you go below certain ride height, alignment can become a problem. Also lower ride height (below certain ride height) makes other parts on car wearout quicker.
Sounds like he knows Skyline weak points, but doesn't know the part names. It can be confusing, as Nissan call a part one name and mechanics call it another name. Then people in Northern hemisphere call it another name i.e MAF = AFM, etc. Confuses me sometimes.
