Greasing Suspension Linkages - Rear Suspension Issues

[QUOTE="skos, post: 1400320, member: 101626"] GREASING SUSPENSION LINKAGES - REAR SUSPENSION ISSUES I was going to go for a ride (1998 YZ125) & found my rear shock was seized. You will need to remove the long swingarm/engine mount bolt #28 that goes right through the frame. Otherwise you can not remove the other #28 (bolt). Lay the bike on its side (don’t forget to turn the gas off) with the nut upward and really soak the nut in release fluid. Leave the bike to soak overnight if it has been awhile, meanwhile go find a length of 1/2" diameter brass or aluminum, something soft. You'll need this to drive the shaft out. All the YZ suspension bushes can be removed using the Motion pro tool and some 2" lengths of 1 1/2" internal diameter tubing. You use this to draw the old bearings out of the swing arm and knuckle joint. Water pipe works just fine. I did not have the tool so I used sockets (I do not recommend) but I needed it fixed ASAP. I found that there was a lot of dirt in #21 (ARM, RELAY). #22(Bearing) did not seem to move. I good cleaning and greasing and it works fine. Use good quality waterproof grease. #22(Bearing) should move freely in #21 (ARM, RELAY) If it does not, get a rebuild kit. Also #25(COLLAR) should move freely in #22(Bearing) again If it does not, get a rebuild kit. Here is the link for the diagram referenced above [url]http://fiche.ronayers.com/Index.cfm/Module/Main/TypeID/26/Type/Motorcycle/MakeID/4/Make/Yamaha/YearID/39/Year/1998/ModelID/6123/Model/YZ125/GroupID/247149/Group/REAR_ARM[/url] Here is a video for greasing a newer bike. In this video, he doesn't grease the main pivot. You absolutely have to remove the swing arm to do the job fully. It needs to be done too for the work to be complete and the problem to be fully diagnosed. Greasing suspension linkages [url]http://www.youtube.com/watch?v=44D11uF_5w0&feature=related[/url] [/QUOTE]
