SuiteSuccess Posted 11 hours ago Report Share Posted 11 hours ago 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 9 hours ago Report Share Posted 9 hours ago 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 4 hours ago Report Share Posted 4 hours ago 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...
