HJ75 steering box - rebuild/upgrade Q's

[dogbreath_48]

My power steering is pissing out fluid pretty badly. I know one of the hp hoses is farked, but fairly sure the 'box is responsible for a fair share of fluid loss (will find out for sure once the hose is replaced) and has a bit of play in it.

So, my questions are as follows:

1. Is there an easy upgrade to a bigger/stronger 'box available (need's to be pretty close to a bolt on affair, don't mind changing pitman arms/drilling a hole or two, fucking around with lines etc.)

2. If i am to get the current box rebuilt, are there any tricks or upgrades i should get done at the same time? At the moment, steering is much lighter than that of my old mans original (still tight/leak free, on 7.50R16's as opposed to my 37x13.5's) HJ75 - could this have been to do with a previous rebuild on my current box? (seem to remember the prev. owner saying it had been done before - a cooler was also added)

3. Roughly how much am i looking at for a rebuild? (expecting a lot) Can someone recommend a reputable shop in Melbourne (pref. eastern) or change-over mob? My experience with run of the mill change-over power steer components has been pretty shit thus far (on holdens )

Look forward to replies

Thanks,

I think i got quoted $750 to reco my PS 40 series steering box, i would think it could be in the same ballpark.

the 60 series box I have on now leaks badly too.. I'm told there is a $10 seal you can replace relatively easily where the on the end where the intermediate shaft connects.

is there any play in your box or does it just leak?

no ideas about upgrades apart from a cooler which you already have.

if you replace your high pressure hose and try that 10$ seal you might find that it sorts our your leaks.. maybe the leaks are responsible for the poor performance? Cheap way to find out.. (enzed charged me about $100 for a crimped hp powersteering hose).
