I only do the pump extend wait, pump extend wait repeatedly until grease passes seal. In very difficult cases these days. Those I use the thinner #1 grease w/moly.Someone reacted to an old post of mine in this thread in which I said I was having trouble getting the drive shaft to extend.
For future searchers, I thought I’d say that I’ve since done this many times, and I think I followed @2001LC ’s advice (in another thread?) to pump it in until the shaft moved, wait a bit for it to return, and then repeat. Eventually the grease started to come through as it should, and it has done so readily every time since.
When Toyota change recommendation in the 200 series. To only pump in grease until first extension is seen and than stop greasing. I change to this!
