Engine/Transmission (1998.5 - 2002) 2001 Steering Lock-Up

[TWatson]

I got into my truck one cold morning last week, started the Cummins up and heard a terrible growling noise from under the hood. Secured the engine, popped the hood and took a quick look. Didn't see anything so I started the engine again and took another look. No unusual noise this time and didn't see anything unusual. Got back in the truck, put in gear to back out of the driveway but the steering wheel wouldn't turn. I took a closer look under the hood and noticed steering fluid sprayed over various parts. I checked the fluid level in the steering pump and it was still at the full level. I figured I had either a steering pump problem or a steering gear problem.



Had the truck towed to the local Chrysler Dealer (mistake) for diagnostic. The service representative called later and said I needed 4 new hydraulic hoses (quoted $1, 200. 00 to renew these hoses!!). I told the service rep that there must be a mistake because I'd priced the hoses on line and the most expensive hose was only $26. 00. Figuring that I was being robbed, I informed the service rep that I would send a tow truck to retrieve the truck and replace the hoses myself. He informed me that a tow wouldn't be necessary as the steering was functional, so I picked the truck up and drove it home.



I have since checked the hoses carefully and do not see any evidence of leakage. The steering seems to be working fine now, but I'm a bit afraid of the unknown.



I'm prone to thinking that the problem is likely in the gearbox hydraulic valve, now. Anyone had a similar problem with their steering or seen this before?



Any info offered much appreciated.



Thanks!

Check to see if the hydroboost accumilator is still active. Run engine then shut oof, hit brake pedal, you should have assist for two brake applications. Just a thought since the reservoir is still full, maybe the accumilator dumped some of its charge of nitrogen. bg

Likely a stuck valve in the hydroboost system back pressured the reservoir and blew the fluid form the cap. Start by doing a system flush to clean out any p[ossible contaminants. That should be done every 100k or sooner if you drive less.
