any info or even pictures of your setups with the reservoirs ect

cheers blokes

Jimny bolts in.
Vitara bolts in with an adapter wedge

[vbr85]

Thanks mate, any model or early model one ?

[vbr85]

Also what pump is best ..

Easiest way is to purchase a complete Jimny setup. Then bolt it in.

Or a complete Vitara setup. Purchase wedge of Zukparts.com. Bolt it in.

Mixing and matching is making it a bit harder than it needs to be.

Remembering that a m series jimny setup(easiest found) pump is made to bolt to a m series motor and wont bolt straight up to g series motors.
need to be a g series jimny setup, hard to find and usually cost more than a vitara setup incl wedge.

Is an m series ps box same as a g series ?

AFAIK yes.

will a standard sierra steering arm work. or does it need to be collapsible steering arm?

Please don't think I'm being rude or condescending, but I think it will be helpful if we get the terminology right. Sorry if this seems pedantic, but much like when people talk about "diffs" to mean anything between the tyres, using the right term for the job greatly reduces confusion.

An arm acts as a lever. There are three arms in a Sierra steering system - the Pitman arm, attached to the steering box, and two steering arms, which are cast into each steering knuckle.
A rod transmits force along its length - so pushing and pulling. There is one rods in a Sierra steering system. The tie rod, which connects the two steering arms on the knuckles together.
A link transmits force between two different elements - like a rod and and arm. There is one link in a Sierra steering system, called the drag link, which transmits force from the pitman arm to the tie rod. Even though the drag link is a rod too, it's always referred to as the "drag link" to prevent confusion.
A shaft transmits rotational force. (like a drive shaft or an axle shaft) There are two steering shafts in a Sierra. One from the steering wheel to the firewall, another from the firewall to the steering box in the engine bay.

If you are referring to the steering shaft in the engine bay, yes, you'll need a collapsible steering shaft, as used in post 1991ish Sierras. You'll need to drill the plastic plugs out that pin the shaft to a set length and slightly collapse the shaft.

With reference to the Vitara steering box, If you use a BenT wedge, you can retain the rag joint near the steering box. if you don't use a wedge and adapt the vitara steering box directly to the Sierra chassis, you'll need a second uni joint near the steering box. this can be another uni from a WT steering shaft. There are a few ways of adapting this in. I have cut off the splined input shaft from a junk manual steer box and used that as a coupler to adapt the rag joint spline to the uni. The rag joint is then eliminated by bolting the two shafts back to back. This method has been certified by an engineer in Victoria as it's all factory parts and requires no welding.

all goood shaft it is!!
thanks gwagen

[Gwagensteve]

No worries. Thanks for taking it the way it was intended.

I haven't personally fitted a Jimny power steering box to a Sierra. I believe it's aligned the same way as a Sierra manual steer box, so you can retain the drag link and don't need an extra uni, but I'm pretty sure it's slightly longer so you need to shorten the steering shaft a little.

Damn it Gwagen. I spent most of the day at work wondering if my SJ50 WT has a collapsible shaft or not. Turns out it doesnt. So I picked one up on the way home

[Zook_Fan]

The jimny steering box is a fair amount longer but still within the realm of shortening the steering shaft by drilling the plastic plugs and collapsing it as Steve said.

The pitman arm on the steering box is shorter than the Sierra box. This is ideal if your diff has been moved forward for whatever reason but do believe it doesn't cause any issues if the front diff is in the stock location either.

FWIW my factory Sierra power steering box was identical to my Jimny's one aside from the pitman arm.

The lower steering column that goes with it is still available from Suzuki for quite a reasonable price (US$20 on megazip), it's not collapsible though.

Grave dig posting but with new relevant information that may help others.
I had been unhappy with my G series Jinmy power steering box in the Sierra.
Steering was slower than I liked and did not feel as good on center as I had expected either. Disappointed.
Then remember reading

So I checked the original manual pitman against the power steering pitman. Jimny is shorter! hmm..
Different spline too. Had a dig around on Megazip and came up with part number 48671-82C00 for leaf sprung Sierra power steering pitman arm.
Amayama had it listed for about $145 inc freight. Much cheaper than Megazip, worth the risk.

New part arrived, yep definitely longer, spline measures the same
Popped old pitman off and fitted new.

First impressions are that it has improved the steering speed and feels better on center.
Much happier now with the install.

Picture below is deceptive as to the difference in length, but I can assure you, this has made a huge difference to how the car feels.
