Drove my 96 U320 today and after is was parked there was a drip under the steering sector. It drips fairly quickly so I am assuming it is likely a hose or fitting leaking. What is the easiest way to access the sector without a pit to work from. I am taking it to FOT Thursday, but would like to check this out before the drive.
Probably a leaking seal on your steering box. It's not uncommon, and certainly FT can remove the steering box and replace seals (MOT can also). Check when the engine is running and keep checking the level in the hydraulic reservoir while you travel. You may want to have a gallon or two of 15W-40 Rotella or your favorite brand of oil on hand to replace lost oil if your trip is a long one.
Having had this sperience with my 2001, 1st time was leaking rapid, was at FOT, had Wayne in front end shop replace the input shaft seal, that solved the drip issue for over a year or two, then decided to have the Sheppard box replaced with a factory reman unit.
Having the input seal replaced was about $450.00 total, not a biggie, but to get to the output shaft/seal is an entirely different story. Due to work load at FOT, had the Bernd Ramspeck shop replace it. Not cheap.
Just had mine replaced about 6 mos ago, it was leaking from the input shaft seal. $700.00 for a Sheppard rebuilt box, $700.00 labor to install. The first one leaked within 3 weeks Second one is fine. As others say make sure the shop that installs it sets the steering stops on the new box, specs say 1/8" clearance on the right and left axle stops, 1/4" is better. If the steering knuckle hits the stops it will blow the top seal out rather quickly. Do yourself a favor and have them show you the clearance. do a search on the form lots of stuff on steering box replacement.
You can also try using Lucas Power Steering oil it has a seal conditioner and a stop leak in it and it does work.You can get it at most truck stops and places like fleetpride ir truckpro.
Yes, as Bruce said, check axle stop clearance as well as getting the seal replaced.
