Suspension Lubrication

I have a 2011 825I with the 14 Zerks for greasing the suspension. I have greased the suspension twice now and each Zerk only takes about 1/8th of a pump before grease starts to squirt out from right behind the bolt head. On my tractor/loader the grease normally squirts out between the bushings, so I am curious if the Gators bushings are clogged.

Does anyone else have the same results greasing their suspension?

Thanks, Dave
