Is it possible to change the shaft seal on a power steering gearbox in place? If so, any advice?
@Richard Cranium, Your seal did WHAT?!
I always have done them in place , on most cars . its usually the pitman that's hard to come off.
how old is the arm , when they have been on for years I usually weaken the arm by cutting it with the torch. and replacing it after. removing it with the puller , then when you remove the snap ring at the bottom start the car crank the steering and the seal pops out.
The service manual shows two seals; a grease retainer at the bottom. Above that is a snap ring, a retainer and another seal. The seal(s) are weeping & does this mean that both need to be replaced and they all can all be pulled with the gearbox still in the vehicle?
Yes replace both.. As mentioned the hard part can be getting the pitman arm to pop off... A screwdriver will pop the dust/dirt seal, then remove the snap ring & as mentioned start the car & crank the steering wheel to full lock... But have a drain pan under it & fairly close or you'll have a mess to clean up...
I have a steel sleeve I turned on my lathe that is the proper diameter to install the seal & the length is such that I use the nut that mounts the pitman arm to push the seal in...
