I just got a '99 SP500. This weekend I tried to grease the drivelines and u-joints. There was no way I could get the grease gun on the zerks. I'm sure that you guys are greasing them and would appreciate any advice.
Thanks,

Jim

 

There is a certain angle/position the yokes have to be in for the grease gun to fit in - I jack mine up on a quad jack and have one of the kids rotate the back tires until the zerk is exposed where the grease gun fits.

 

I've found also that a lot of them are easier to reach if you take the wheels off.
