Power steer box leak AGAIN

[billyvanboheman]

Just after some advice on whats under the top seal housing on the power steer box's on the Isuzu's.

I replaced the seal last Sunday and it was fine for two days, then a slight weep has turned into a full on leak, worse than before.

My next plan is to take off the top seal housing, to get the only slightly used seal out, and put a new one in with it off so I can check everything properley!!

What I need to know is what surprises am I likely to find under the housing? gears/vanes??? or is it just a seal housing and inlet point for the pipes??

Photo of the box concerned below.



So far I have checked that the shaft was all clean when I put the new seal in, so I'm stumped as to why it's leaking without closer inspection.

Also I have folded the dust cover back for the photo, it's not like that normally!!

I think if you take that cover off the input shaft comes with it and all the little ball bearings in the recirculating ball system circulate themselves around the steering box and you have to take it out to reassemble it.Ask Garth,he's been there more recently than me.

Not recommended to try and take the top off!!! Mine still in pieces after a few years sitting on the shelf!!
Have got another one I picked up cheap fitted to the truck now with a new shaft seal and no trouble after several thousand km's.
Is possible to re-assemble but definately tricky and I haven't had the patience to attempt it, or the need now I have a spare.

Be careful when fitting the new seal that you don't pinch any parts of the inner groove as it is the pressure pushing this against the shaft that seals it, any damage to the lip of the seal will result in a leak. Suggest you put a smear of vaseline on the seal prior to fitting it. you can also try some Power Steering Stop leak fluid instead of normal fluid if leaks persist. helps with old seals.

The input shaft is prone to rust. This will eat seals very quick. The first time mine was repaired it was done with a speedy sleeve which lasted 5 years. The second time the shaft was rebuilt useing a metal spray.
