I have the OME Shackles and bushings on my truck and for some reason when I went to shoot grease in there today I got a few pumps in and suddenly it became hard to pump. I gave a good squeeze expecting some grease to ooze out of somewhere and instead I catch a glimpse of the bushing end warping and bulging. But no grease escaped, I took the zerk fitting out of the shackle pin to see if the pressure would dissipate, a little oozed out of the area but the bushing stayed bulged.
What do you think is happening here? I thought this was supposed to be easy maintenance. Maybe I should have kept pumping but it just didn't seem right. I am using a Valvoline NLGI #2 Lithium grease that is fortified with Moly so I think that is correct. The Valvoline container said that it was good for CVs, Driveshaft u-joints, Suspension, Brakes, and most chassis greasing. Any ideas guys?
