SuiteSuccess Posted Wednesday at 12:54 PM Report Share Posted Wednesday at 12:54 PM Just out of curiosity (I’m taking to the shop), has anyone replaced the top seal in their unit and how difficult was it?

Jaydrvr Posted Wednesday at 03:26 PM Report Share Posted Wednesday at 03:26 PM It's really easy. A LOT easier than changing out the box, but a lot of shops would rather make more $$$$ by selling you a box, plus labor to install it. The super easy way is to expose the seal and then momentarily crank the engine. The power steering fluid will blow the seal out. Or you can just use a pick to dig it out.

I would assume the main seal is NOT the red rubber grommet showing in pic #2.

On mine, the seal was about 3/8" (?) deep from the top of the box to the bottom of the seal. The red part you see may be part of the retainer?? Or it may be just a protective shield. I can't really tell. Jay Quote Link to comment Share on other sites More sharing options...
Deezl Smoke Posted Wednesday at 07:43 PM Report Share Posted Wednesday at 07:43 PM I've always had terrible luck replacing worn seals on a rotating shaft. A telescoping shaft seal, not a problem. But the rotating shaft seal usually only goes out when the small contamination in the fluid cause a wear spot on the shaft. New seals on a worn shaft usually only last a short while. IMO.

New seals on a worn shaft usually only last a short while. IMO. Mine lasted several years until I replaced the box because the output shaft was getting too sloppy. It did buy me some time and maybe a 100,000 plus miles. But yes, the shafts are often too worn to fix. Jay Quote Link to comment Share on other sites More sharing options...

SuiteSuccess Posted Thursday at 02:19 PM Author Report Share Posted Thursday at 02:19 PM Found this, Jay. He does it just like you described. I don’t have the tools to do this so will take to shop even though it looks like a fun project. Question for future reference. What type grease is he using?

After driving 250 miles without power steering and burning up the $600 power steering pump in the process, I opted to take their advice.

I don't think you would need any specialized tools. You can use an appropriately sized socket to drive the new seal in. I have seen use specific grease for seals, but for such a low tech application, I would just use plain old chassis grease from the grease gun.
