Too much grease in the slip joint
Hello I was greasing the shafts after changing differential and transmission fluids (90k miles) and everything was going OK. I fully realize that the slip joints only needs a few squeezes of the grease gun, while the U-joints like to have some grease come out. However, my brain was on autopilot and I started pumping into the forward slip joint, I must have pumped 12-14 times before I realized.
I removed the zerk but nothing came out. The FJ is on 4 jack stands and there is no weight on the front axle, all the tires have been removed; it seems the front slip joint is fully "compressed" in this configuration. Am I OK or should I do something to avoid hydro-lock the slip joint?
PS now that I have the FJ up on jack stands, tires removed, what should I look for as preventive maintenance, other than what's written in the manual?
