Hi, I have a 2002 Prado, last of that shape, owned since new. I'm an ex aircraft mechanic.
The front propeller shaft universal joint has a grease nipple as part of an alloy boss that can rotate 360 degrees to facilitate getting the grease gun tip coupler in there.
The nipple has been a bit of a pain to get the grease into it over the years, but yesterday, it would not take any grease, just spewed it out of the sides of the grease gun coupler. I tried three other guns with the same result.
Checked that the nipple sealing ball was free with a needle, and this also confirmed there was no built up pressure from excess grease behind it. So I assumed the exterior surface of the grease nipple is worn out of shape.
The nipple appears to be a standard screw in type, with flats to take a 7mm socket. However, it would not budge at all. The flats are the worse now for my effort , and I will need to get the shaft on the bench to get at it better and maybe apply a bit of heat to the boss.
Before I do that, can anyone confirm that this particular nipple is in fact a normal screw in type ? Again, its the nipple that part of a rotating alloy boss in the front prop shaft universal joint.
I can send a photo if required.
Thank you,
