Hi all,
Just got me 30 X 9.5 R15's and put them on but on full lock they rub against the chassis, I was advised by someone on here that these are the best sizes for the my Fourtrak, is there anything I can do like put in spacers to remedy this problem?
Also, when I was changing my wheels over, because Im new to 4X4's and the whole manual free wheeling hub arrangements, I noticed when I turned the passengers wheel to LOCK and turned the wheel the front drive shaft would turn, and when I turned it back to free and then turned the wheel it didnt move, this kinda summed up the whole FREE and LOCK system for me.
But when I went to the drivers side, the mechanical switch from FREE to LOCK on the hub seem to move around and around and not sit on either LOCK or FREE, and in either position the drive shaft never rotated.
This got me a little worried thinking my 4WD wouldnt be working. So I jacked up the whole truck, turned on engine, engaged 4WD and every wheel rotated. Phew I thought!!
But Im still not convinced this is ok, please can somebody explain what might of happened to my drivers side FREE WHEEL HUB, and why the drive shaft rotates with the passengers locked and not the drivers.
Many thanks all...
Have a good bank holiday....

1st of all don't worry about
1st of all don't worry about the tyres rubbing the chassis. They'll only do it at full lock, and you should not be going fast enough to do any damage when at full lock anyway. You'll just gat a couple of shinny patches on the chassis.
As for the FWH though. With the wheels of the floor thw 'unlocked' wheel could turn anyway from just the friction in the hub, as there is no resistance against the wheel to stop it. When you turned the wheel and the prop didn't move, did you have the other FWH locked? If not the drive shaft in the other side of the axle could be spining instead. This is not likely, but possible. I would say that the 'mechanical switch' just spinning round would meen the big spring inside the FWH has either brocken (unlikely) or come out at one end (more likely). If you unbolt the end of the FWH (6 8mm? bolts, or Alen bolts on later traks). Make sure the FWH is set to 'free' befor taking this out, otherwise you may pull the spring out yourselr. There should be a spring atached to it, with a metal 'ring' attached to the other end of the spring. This 'ring' is splined inside, and out. This is what slides in and out to mahe the FWH lock, or 'free'. If the spring is whole, but not attached at one end or the other, you should be able (with some persavirence) to re tread it into the two sections of FWH you have removed. Grease the interiour of the FWH, and re-asemble. You will find that due to the shap of the splined 'ring', and the spacing of the 6 bolt hles, that the end of the hub will only slide in in 3 positions, and that in only one of these will the bolt holes line up.
Any veiws expresed in this thread by me are purely from my own experience, and (sometimes) falible memory. Hope my comments help, but please don't take them as gospel.
Other FWH Locked?
So you'll saying at the time when the truck was on the floor and I only had the passengers wheel jacked up I locked the passengers side and when the I turned the wheel tha driveshaft turned as well, this is normal?
So then when I put the passengers side back down and moved around to drivers wheel, jacked that up, removed wheel, put new one on, then locked the FWH to do the test again, if I'd left the passengers LOCKED then the drive shaft wont turn, like it did on the passegners side when I did the test?
Im pretty sure (99.999%) this was the case that the passenges was still locked, so perhaps there is nothing wrong with the mechanism then?
I did have a go at taking off hub, but could only un-screw the back 6 studs and not the front ones, as the allen bolt heads have become worn that a key wouldnt fit proper, would it be ok to drill these bolts out.
When I unbolten the 6 rear bolts on the FWH obviously the hub wouldnt come off but I did manage to move it from side to side a little, after realising it wouldnt come off, i'd put the bolts back in tightened them up and the mechanical switch no longers just spins, it locks into place like the passengers does in the free and lock positions. Is it likely I could of fixed the hub, or was it not broken in first place going back to the test I did still having the passengers FWH locked?
Is there a test I can do to make sure the 4WD is working like it should?
Again, thanks again for your help, its been much appreciated.
Cheers,
Shaun
If your not convinced by the
If your not convinced by the tests you've done, you could unbolt the rear propshaft, and take it off. Then put the car in 4WD, with the FWH locked. The car should drive on the front axle. There is a diffrent version of this test, which does not require removing the prop, but it could cause dammage to the car if not done properly. What you can do is put the car in 4WD, with the FWH locked. Jack up the whole back axle. Stand the axle on blocks of wood, so the rear wheels are just of the ground (1-2cm). Then drive the car forward. If the front drive chain is good the front axle will pull the back axle along / off the blocks of wood. As I saud this test could cause damage if not done carfully.
