Help! I'm putting my LH torana rack back together and thought I had better replace the outer bush in the rack which I assume is the original steel bush. Bought a kit which includes a nolathane bush. This bush looks way different to the original and I have no idea whether it will actually fit or not, so I'm a bit dubious about pulling out the old one. Is this new bush OK? (see photo below) If so, how is it held into the rack body? The old one has a pin through the housing as shown on the photo. Hope the photos below show what I'm talking about.
Any help would be great!!!! Cheers, Matt

The blue bush looks like a Commodore one.
The 3 lugs around one end clip into an annular grove in the Commodore racks.
I'm not sure about Torana.

Thia is what a Torana LH LX one should look like.
The clear one on the left is possibly a original GMH one (i have seen these in different colours too).
The blue one one on the right is Noltec replacement.
They look very different but fit just the same.
At the time I did mine, the clear one felt it was made of tougher material and had 3 high spots(friction pints) in the inner
circular hole that the shaft rubs and is guided. The outer is is more hex shaped and allows the gear oil to flow to the boot side.
The Noltec one felt slightly softer but has a hexagonal inner hole allowing 6 frictions points to rub on shaft
and allows oil to pass throught the inner hole . The outer diameter is cirular and was a tight fit.
Dont really know the long term effects of this design change in the bush.

THANKS FOR THE INFO. AFTER REMOVING THE OLD BUSH I HAVE DISCOVERED THERE ARE NO GROOVES IN THE HOUSING FOR THE LUGS ON THE NEW BUSH TO FIT INTO. ANY IDEAS WHERE TO FROM HERE? CHEERS, MATT

From what I remember those six lugs on the blue bush fit into the groove shown in the picture below just like the 3 lugs on the original bush. Of course the rack needs to be removed from housing.
DATTOMAN, which one are you saying is the wrong kit?
The noltec number for the kit I got was N11049.
Good luck finding a Kit31K and that part number is also same as Nolathane but they simply dont make it anymore or they didnt when I was looking.

Hi again guys, it is actually kit31k that I've got (old stock that rarespares had). Anyway after taking the old steel bush out it does not have any 'lugs' at all, and the housing has no groove to allow the new plastic bush lugs to slot into.

Is this rack actually off your car or did you buy it?

Maybe that is the problem?
Maybe it's not LH?

Dont know how much this will help you but I just went out and had a look at a LX rack which came off a sunbird with the
first generation RTS(pre UC RTS) with part number 9942632 and date stamped 24-11-77 and it takes the same bushes I pictured
in the earlier reply which has the groove in the housing and are also the same as the UC rack.
I also have an LH rack part 9932244 but unfortunately that one is still mounted on subrame, in working condition, full of oil and sorta
cant get to because how its stored. It may very well be different as you are suggesting.

Thanks for all the suggestions guys - I can't read the serial number on the rack unfortunately. I'm stuck with this rack so I'll have a groove machined in it. Hopefully this info is helpfull for someone else in the future. Cheers, Matt

Apologies for the thread revival. A Google search is great for bringing things back from the dead 
I'm looking at my own steering rack, trying to work out if I need to replace the outer bush, as discussed in this thread. How much play, if any, should be in this bush, before you need to replace it? Mine seems to have a noticeable amount of side movement, which I'm sure probably shouldn't be there.
Given that it's now 2014, 5 years on from the last post in this thread, what's the "best" replacement for this bush these days?
Cheers.

The bush should have minimal to no play at all (oil clearance),it is on the long side of rack and on the off road side and cops a hiding if driven on our roads.
Just been looking at this thread again and it has been said that the casting #s may not indicate ratio but just looked at the junk laying around and
on all 3 UC's the # is 277 (last 3 #'s),the LH/X racks are 244,froks me what the 632 came off but if the ratio/cast #s are right seems like a good one for the UC.
Had to replace that bush not long ago and thought they were all the same,turns out that the ones i got made up for the LH about 10yrs ago would not push in to
the UC rack,reason being that the housing and the rack end shaft on the 277(UC) are different sizes compared to the 244,dont remember the ID of the 244 but the rack end shaft on the 244 is 25.4mm aprox compared to 25 on the 277...probably .4mm smaller on the ID of UC rack to keep things even.
nothing wrong with digging up old threads,you never know what will come up.
Better off to get some made as per original shape with the 3 grooves for oil flow,tried some of them other ones,they just don't last,cheaper to get 3 or 4 made at once,can't remember the material but it was something like "lubron' or some oil resistant pre-lubricated nylon stuff.
