The tilt cylinders on my 2001 LS180 need to be rebuilt as they are leaking oil past the seals during operation. I have already taken one of the cylinders apart to rebuild, but am having a difficult time tracking down the correct seals/kit. Is 86570931 the correct kit number to have all the necessary seals, wipers, o-rings, etc.? It is hard to tell from the photos or lack their of online what all is included and I would like to be confident that I am ordering what is needed. Also, any rough guess on what they should cost if I can find a local hydraulic shop that will sell them directly to me?
