Finally did my PTU oil change that that Service department couldn't figure out how to do.. Saved me money.
bought this pump at autozone
http://www.autozone.com/test-scan-and-specialty-tools/fluid-pump/oem-fluid-transfer-pump/94647_0_0/It got a big work out today. As i used it to do the PTU service on the SHO and the front and rear diffs and T-case on my 77 dodge p/u
only complaint with the tool is the provided hose are a bit soft under suction but that has its benifit of being flexiable when inserting into fill plugs.
They way i did it was just jack up the passenger side of the car. remove the plastic cover for the extra room and to look around. Got under the car with a 3/8 drive ratchet got it broke loose. Then got a short 1" 3/8 drive extension to help thread out the plug the rest of the way. Used the suction pump i bought. then dropped the car back down and got a little more out. Kinda handy with the Liqui molly fluid i bought. If you seen the photos i had uploaded before. the 75w-140 had a little pop out fill spout. Well that spout on the bottle and the suction pump inlets matched up.. all i did was swap hose ends on the pump and attached the pump directly to the LM oil jug. pumped from the bottom of the PTU up so it pushed some more of the old fluid up and out as it filled.
I only got about 8oz at first. Obviously this was was a bit more messy and i over filled a bit and let it drain out with the car sitting on the ground. Once that stopped, raised the car back up reinstalled the plug and cleaned up the mess
My fluid wasnt horrible sludge like some peoples. That made me happy. But it did have a grey/silver tinge to it indicating to me a lot of metal in it. Still poured fairly easy.
