Hi,
After a bit of technical advice from someone who has more experience with Conqueror UEV490 suspensions. The unit that we own is a 2012. We bought it second hand (maybe 3rd or more, who knows) and it obviously has done a lot of work, let's say it is well travelled. We have had it 4 years and have just completed a 5000km trip Sunshine Coast via Broken Hill, Peterborough etc to the shores of Lake Eyre and then returning via the Strezlecki Track which was pretty rough, western Queensland to home. Upon out return I noticed a badly worn right tyre, inside edge, worn to the wire reinforcing. Yes, we were lucky but even though we did hit a few bulldust holes fairly hard on the Strezlecki I am surprised that these incidents would have bent an axle.
The questions. Do axles on Conqueror UEV490 bend and is this likely to be the problem? Is it possible that the suspension arm would be twisted? There does not seem to be any play within the suspension bushes but who know, could that be the probelm. I am pretty sure that we did not have a problem prior to the trip and things seems all ok at the mid point. I did think that the right wheel was leaning in a bit as I walked towards it in The Thagomindah caravan park but by this satge things were covered in mud, dust etc so I did not dwell on it but I was right.
Waffled on a bit. Any advice would be welcome and if it is a bent axle where is the best source of a new one or is it possible to get it straightend.
Regards,
Kim. PS It was a great trip despite the dust.

Hi Kim,

Not sure if the axles bend but everything is bendable! (from my own experience[biggrin]) But if the bushes & shafts are worn One presumes that they will. The original setup from Conqueror is not good and in my opinion a very weak point. I recently upgraded mine myself after noticing the same abnormal tyre wear as yourself & after purchasing a kit from Mark at tough touring I could not be happier with the new setup on my 2013 490 evolution, as well as being able to grease it too. There was absolutely no way I was ever going to get Camber and tow  in/out correct with the Original setup that was on there, I had to go to a machine shop and get a new pair of adjusters made up as the supplied ones were drilled incorrectly thus having no full adjustment (see first photo) it was not until i put the 2 concentric drilled ones on the same axle that i could achieve correct adjustment , and as we all know Conqueror Australia are soooo handy in these situations [rolleyes]. It is not a pleasant job doing this on your own but if you wish to check it yourself before making any big decisions I used a simple angle gauge against the brake drum for the camber and a laser measuring tool between some angle iron drilled and bolted to the brake drum for the toe in. All that I could find out from Mark at Tough touring, the internet and this forum is toe in should be approx 0-3mm (I ended up with 1 mm) and 1/2 a degree camber However for the life og me i could not achieve this and settled for just under 1 degree to which Mark assured me was fine. Anyway good luck and I hope that this helps a bit.
cheers Lars

Hi Lars,
Thanks for getting back to me and sharing your valuable experience. I will check out the 'Tough Touring' option as it sounds pretty good. I got the axle out early this evening (it came out surprisingly easily but there was not a hint of grease on anything so I am not very impressed with the standards of assembly). Rough measuring is suggesting a bent axle. I'll keep you posted with how things go and I'll take some photos including the state of the tyre. Gee, we were lucky it didn't blow!
Regards,
KimP.

Yes the Quality control standards leave a whole lot to be desired. The whole axle design is complete busted arse, something that you would expect on a bullock wagon [smile]..Good luck & keep us posted.. cheers

Hi Lars (and others),

Some photos indicating the state of the right hand tyre. The total trip was about 5500kms but I think that this wear occurred in the last 1800-2000 kms as the only portion of the trip where the suspension received any stress was on the Strezlecki Track and as I have already said, if that is where the damage occurred I am surprised that the Conqueror was not up to what was served up. Note the surface corrosion on the axle shaft. How anyone can install such a part without any grease/never seize is beyond me. Lars, I take it from your comments that there is some adjustment available in the original Conqueror suspension swing shaft. Is that correct?

Regards,
Kim.

If your setup is the same as mine the toe in/out and camber is adjusted on the front shaft of the suspension A frame by adjusting the concentric tabbed washers as in my first photo. Personally if you have gone this far I would be removing and checking those also. A good tip is to mark the positions of the tabs before removing for a reference when reassembling. 👍

Kim , have a read of a few previous posts also regarding wheel alignment issues.

Hi Lars,
Talked to Mark at Tough Touring. He certainly knows all about Conqueror suspensions. I've got 'new swing arm' shafts (my terminology), bushes (originals OK but will replace) and other auxiliary components en route. The axle was OK and the original shafts were moving freely (they actually had been greased) so the chassis welds are all good. The outside swing arm plate hole is out of round on the right (haven't got to the left yet) but not extreme and will be drilled oversize to match the new shafts. Even though the right side is the problem I will redo both sides of course. Plus the components all get a good cleanup and repaint. The actual aligning is going to be fun!
I'll keep you posted and thanks for your help. It seems that this is a common problem with Conquerors so I think that there will be many others who quietly follow your advice.
Regards,
KimP.

Good luck Kim yes the wheel alignment is sooo much fun 🤮 in and out in and out etc another good idea is have a look through the forum and maybe get the part numbers for the nolothane bushes for the shocks and change those and bolts too?? Have fun 😂

Hi Lars,
Using the new parts the best I could achieve was 6 mm toe out so I welded up the off centre holes and re-drilled them more off centre. And it worked. One millimetre toe in and cambers of .4 (right) and .2 (left). Thanks for your help which was invaluable in sorting this out.

all,

our 2010 490 has recently been to Mark at Tough Touring (Melbourne) for a complete overhaul underneath. I'm confident now that its better than it was when it was new (I'm the second owner)

Mark has replacement shafts and bush's and replacement eccentric bits for adjusting the alignment, I think he probably has these "of the shelf" now so no need to run down to your local engineering shop to get new shafts or bush's turned up

Definatly worth talking to Mark if your going to tackle your alignment problems (or the squeaking shaft issues) and buy a full kit, he certainly is no stranger to the underside of a 490

mine was only done near the end of May and has less than 3,000Km's since (including about 1,000 Km's of western NSW dirt roads and station tracks) and shows no sign of wear and tows great

Hi Garry,

I got all the parts (bushes, shafts, adjustment keys, nyloc nuts) and a lot of helpful hints from Mark. Hopefully the alignment is now as it should be. It seems to be a common Conqueror fault with many of the problems originating from the initial assembly which is not so good!

Regards,

Kim.
