When I remove the PS on my 88-91 Civic is the rack a self lubricating like 95+ Models.

Now I know what your saying. 4thgens don't have PS. JDM Racks did and I in the process of a RHD COnversion. (Save your flaming and banter, I don't need to hear it, the clip was CHEAP (almost free) and I have the ability and tools).

 

no idea but i would assum they are

 

I was just gonna pull the line until I learned from the New SteathMode Product about 5thgen and up being self lubed!

 

even if it is self-lubed ,without the line pressure it`s going to wear out eventually. seen it happen on a few 5th gen including mine.
