Power steering problem - UCS69 Wizard

Postby TimboTheKiwi » Fri Mar 20, 2020 9:18 am

I have a 96 UCS69 Wizard 4JG2.

Recently the PS system has been doing some weird things. About 2 weeks ago I noticed a minor sound similar to that of low ps fluid. I opened up the ps reservoir and it was virtually full. I topped it up a little anyway. A couple of days later I noticed the sound returning and some fluid (I assumed the extra I had added) coming out of the top of the reservoir. Inspecting the reservoir I noticed a small relief hole which they must have designed should the fluid level exceed that of the reservoir, I am assuming. I looked for bubbles for a clue of air entering the system but couldn't really see any. I checked around the low pressure side of the hoses for any leaks or cracks and cannot see any. I put my head down by the steering box for any sign of leaks and cannot see any. The pump has been rebuilt in the last 6 months so can't imagine anything there being a issue.

Has anyone encountered this problem before? I guess the next logical thing to do would be perhaps removing and inspecting the steering box...?

Cheers in advance!

Is the fluid pink or red? Pink will be suspended air and a leaky pump the most probable cause

Last time we had that issue, it was the pump. the vanes and housing were damaged. Getting the steering box out is a real pain if you don't have a pitman arm puller.

Following up from this...about 2 weeks after posting this I heard a rattling noise coming from the pump. I popped the hood and could see a huge amount of play in the pump pully. Stopped the engine immediately, pulled the pump and took it into a shop. The guy said if it had been on there much longer it would be a new pump but luckily it could be rebuilt, so $200ish later installed and no leaking or issues. So I guess air was getting in past the pully and forcing air up into the reservoir somehow (where it was leaking).

fyi I don't know if 2 is needed but I have only 1 ps belt.

second belt is more for the aircon. If you had left it much longer he should of said the shaft can break sending the pulley through the radiator. Been there done that
