MAYBE the pump hasn't got the PSI capacity for turning the larger rubber. Does the pump 'buzz' a lot when turning the steering? It could be bypassing internally..

maybe have to upgrade ya power steering pump,
my thought were cause theres a lil to alot more tyre to turn it put it under far more strain
then if it where back on the vns smaller tyre

will the GQ pump adap onto the vn motor?
its in the same spot isnt it?
same side and all from memory

The squealing is from a poorly adjusted belt.....

retighten the belt and try again .......

also is the belt a new one or the one from the motor, maybe replacement time for the belt......

a handy can of spray stuff called "GRIPPO" / " BELT GRIP" is availiable from 99% of auto shops...... helps with sliping belts really well, I use heaps of it as the Patrol is usually in wet conditions and the 'rubber/steel pully/ & water combination really does SFA for belt life and grip !!

I'd bet it is a loose belt too, had the same problem on my patrol. If it is a Saginaw P/S pump it will have plenty of grunt to turn the larger tyres. My Saginaw pump is off an old 202 powered Commodore and tyres my 35s with ease, as long as the belt is tight.

Ring Driveline Services at archerfield they will know all the specs on Both p/steer pumps on 3275 7650 for they rebuild them on site. They rebuilt my FJ40 manual steer box and even with 35's on 10inch rims and a wrong amount of lift it didn't wonder on the road.

Pump stopping is a different story, hold at fast idle to see if it turns,
then it is either pump not highenough output at idle or it may be bleeding around vanes.
