I am going to replace all 4 u joints on my 98 D1. The current ones are making a little noise but seem to be fairly tight. I also noticed grease will not come out of all 4 seals and it is very hard to pump grease in (only comes out of 2 or 3 seals). What brand and P/N can I use from a local parts store such as Advance Auto?

 

The NAPA precision #344 for all 4 of them

 

The Neapco 1-0005 is what Advance Auto Parts sells, about $13 each.
Order them online, get a extra in case you mess one up, or to have as a spare, maybe a couple of National A37 hub bearings, an order that totals $75 or more and you get free shipping.

 

Thanks for the info. I will probably go with the Advance Auto ones as they are always sending me coupons. Any tips in hammering the old ones out and new ones in? I saw somebody using a couple sockets to help push the old caps through and the new ones in.
