Replacing a pitman seal is not as difficult as it may seem.

First, you need to jack up the vehicle and remove the steering gear from the frame or axle. Once this is done, you have access to the pitman arm. To replace the seal, you will need to carefully pry off any existing seals with a screwdriver.

Next, clean out all of the old grease and dirt that has built up in between where your new pitman seal will go with some brake cleaner or mineral spirits. It’s important that everything is thoroughly cleaned before installing your replacement seal so make sure nothing remains on either side of where your new part goes!

Finally, using an appropriate lubricant such as silicone-based grease or Vaseline, apply it around each edge of your new pitman seal before pressing it into place firmly but gently until it’s secure within its housing unit.

After replacing the part be sure to check for any leaks by running water over both sides of where your new part was installed – if no water passes through then you’ve successfully replaced a Pitman Seal!
