Chiquidrac Posted August 1, 2015 Report Share Posted August 1, 2015 Hi Guys, I have use the search function here but can't get the solution to my problem, I am trying to replace the UJoints on my 1981 510, I have the shaft down and after looking at the joints I notice that they don't have the normal clips, instead there are some kind of star clips on them I also look inside the ujoint for the clips but nothing, Can some one tell me if there is a special tool to get the clip off or is this a non serviceable driveshaf as the one in a previous topic? Thanks in advance. Quote Link to comment
datzenmike Posted August 1, 2015 Report Share Posted August 1, 2015 Those are non replaceable joints. They are staked at the factory. A shop that specializes in driveshafts can remove and replace them but it isn't cheap. New grooves will need cutting so the C clips can fit. After this changing them would be easy. What I did on my B-210 was just get a used shaft from a wrecking yard. 1 Quote Link to comment
Chiquidrac Posted August 1, 2015 Author Report Share Posted August 1, 2015 Ok, Thanks Mike that helps a lot, and it saves time too, I think I will go the wrecking yard direction see if I can find one. I just sold my 1979 210 wagon but the guy took the engine and transmission to put it on his Spitfire so i will ask him to measure the shaft length and width to see if I can use that. Thank you again 1 Quote Link to comment

datzenmike Posted September 26, 2015 Report Share Posted September 26, 2015 Unfortunately these U joints don't come apart. They and non serviceable. Is your manual a Nissan FSM??? or a generic Chilton's? Quote Link to comment

David F Posted October 1, 2015 Report Share Posted October 1, 2015 Yes it is the factory service manual given to me when i bought the car 6 years ago from the original owner. Manual was issued August 1980 publication no. Sm1E-0A10U0 Quote Link to comment
datzenmike Posted October 1, 2015 Report Share Posted October 1, 2015 This one would have been printed in Japan for Nissan. About 1 1/2" thick. Quote Link to comment
kdennis Posted October 1, 2015 Report Share Posted October 1, 2015 Those may be replaceable. There are replaceable ujoints for "non replaceable" ujoints. The retention of the cap on the replacement is done with an inside snap ring. You need to measure the cap diameter and the distance inside to inside of the yoke ear (as if there was no joint in it). Refer to the link and see if they make a joint that matches your cap and stack up. The 510 isn't listed by application, but I believe you will find a match. http://rockforddriveline.com/replacem.htm The "stakes" are just little areas of displaced metal from the yoke. You can either grind out the stakes (only the tab of the each little square that lays over the top of the cap) with a small die grinder and remove the ujoint as usual. I just force the cap right past the stakes, and then go back in with a rat tail file and remove anything that would keep the cap from centering up upon installation of the new joint.

datzenmike Posted October 1, 2015 Report Share Posted October 1, 2015 For the C clips to work you need an inner groove for them to clip into. If truly non serviceable they won't be there so no way to secure the U joint in place. Quote Link to comment
kdennis Posted October 1, 2015 Report Share Posted October 1, 2015 Out side snap rings require a groove. Inside snap ring joints have the groove on the cap. The snap ring goes onto the cap on either side and is up against the flat surface on inside of the ear of the yoke. All inside snap ring joints are like this. Old dodge, the standard chevy/saginaw/3r inside snap ring joint. If the inside to inside of the ears of the yoke and the cap diameter are on the chart, they are replaceable. no special machining required. 1 Quote Link to comment
