Axle Direct Recovery

[Unit1]

I am considering installing the Axle Direct Recovery system sold by YiCaN Pty Ltd on my 1997 D1. I would appreciate any comments by those who have actually used this system. I have viewed the websites that explain the system. Any comments on the installation process would also be appreciated.

I think that almost all recover from the chassis because its stronger and you dont need to get under a stuck 4WD.

Put simply - Dont!!!

Places too many forces on an area not rated to handle them... Front axle and mounts arent made for this forward pull and will place stressed that can and do damage the mountings....

A better system is recovery points on each chassis rail and a bridle to join them... (Easiest is a tree trunk protector between the 2 points)

Like everyone else has stated do not recover from the axle - I have personally seen a few vehicles with their axles ripped out from under them buy trying to be recovered by the axles.
Use chassi mounted recovery points.

Responses to above:

Slunnie: The cables are pre-attached. One doesn't need to get underneath during the recovery.

Tombie and Crash: If you are putting that much pull into a snatch recovery, I think you're doing a recovery that should be done some other way.

I'd believe you if it was on a leaf sprung car but the the huge radius arms underneath, I doubt it.

BTW, Phil isn't making them any more - unless he has restarted. I've been asking him for one on and off for some years.

given that all your drive and all your braking goes through those memebers and usually when you recover from them your not only pulling but lifting the vehicle..

whats the problem?

youve seen the tilt trays that use the axle hooks to tie your vehicle down, how much stress do you reckon that puts on the suspension?

did you see that Jeep video that was doing the rounds, I think they recovered from the axle housing...wasnt very pretty :eek:

This might not be the correct link but its not a good way to tow.

I would have expected that if the tow was attached to the axle that the axle would have been pulled forward and the chassis and body would have stayed put.

Isn't that the opposite of what happens here. The body gets pulled forward and the axle and wheels try to stay put.

Doesn't this video present an argument for connecting directly to the axle?

That's what I was thinking. The axle really needed to be lifted as it was almost entirely immersed on the side closest to us.

recovered from the chassis. if it was recovered from the axle it would have taken the wheel out from under the vehicle OR when the axle snapped the line would have come clear from the fracture and left everything stopped apart from the cable which with any luck would have taken out one of the potential darwinites that keep standing in the whip area of the line


but even if thats not the way it happened, chassis, suspension tied off of the roof rack it still leaves out the blindingly obvious.....

1. a shovel works better in those situations than any amount of pulling I dont care where you hook up to you do what they did you're going to break stuff.

2. the best recovery point to get that out was the rear tow hitch or rear axle going backwards up the hill thats on the drivers side of the cherokee.

My money says he sheared the axle mounting bolts

I didn't realise there were always cables under there.

Also, the radius arm probably isn't the weakest link, especially the way the classics have their links mounted to the chassis. Probably ok for light and general recovery but just not what I would do to my 4WD.

I think it is a great idea.
Q\What is usually stuck in a 4x4.
A\The axle/wheels/ diff

If the body is stuck you are going to rip the hell out of it anyway towing from a tow point.

ALL of the force of snatching etc must go to the stuck point ie the axles via the axle mountings if you snatch off a recovery point.

If recovering from the axle the only mass is the 4x4 (plus inertia), not multiplied as with a snatch strap.

And I can assure you that the chassis mounts on a Rangie are about the strongest part of the car.

I drove my LH leading arm mount back 20MM in the 2000 Nissan Trials ( I assume whacking a rock at speed in the Rock Garden) and the power and heating needed to restore it was a LOT.
BTW I agree that the Cherokee was snatched from a Recovery point, so is the greatest argument FOR the axle system.

I'm not going to continue to debate this because my opinion is...

Its your vehicle do what you want ;)


But I won't recover a vehicle attached to the axle if at all avoidable.

I've also seen the front bolts shear off the axle using the axle mounted bridal first hand..

And also seen the same vehicle earlier that day caught up on the cable.

[Zute]

Can I just say, snatching that jeep was wrong, anyway you look at it. To me it looks like they where caught in a flash flood. there are no tyre tracks into it.
It should have been lifted free of the mud with an exhaust bag first. Dropping the tyre pressure down to 10 lbs and they might have driven it out. But no, Yanks think Horse power is the answer to everything.

[tempestv8]

That video is proof that it was definitely NOT an axle recovery. If it were, there is no evidence of the cable arrangement for the axle recovery product. Nor is there any evidence of anyone clearing the mud to attach the cable to the axle.

Looks like the Jeep was stuck on a rock and they pulled it so hard forward that it pushed the axle back so hard that it broke.

[Blknight.aus]

black soil mud can provide that much drag on a vehicle..


if he came down the hill and turned onto the mud to try and get across (how he expected to climb out I'll never know) you could quite easily get yourself stuck in the exact same position he was in in the northern territory or the mid west coast.

[PhilipA]

I have found that under these circumstances you need 2 recovery methods. It can be a wide variety of methods but you need two eg snatch and hi lift, winch and bullbag, snatch and shovel and mats,etc etc

Our whole club got stuck one day in "vomit" country near Mudgee.

There was a crust about 80MM deep and under was porridge.
First to bog was a Disco 1 with a 12,000Lb winch. He tried to pull out but just sailed along on his belly , building up mud to almost window level on one side. BTW the first attempt was by snatch which broke at the loop and took out the recoverer's tailgate.

We placed my bullbag under the front , inflated it to lift , then rolled over it with the winch. After a short time the suction broke and the front lifted out.

IMHO the main problem wit the Cherokee was that they were pulling sideways against wheels that were fully sunk.

My interpretation of the material they were bogged in was overburden from a mine. Fine silt accumulates at the base of the "mullock heaps" and has no structure to give a base. I believe they would have eventually got it out backwards if they had shovelled and persevered. BUT who knows.

I agree - if it's the axles which are stuck, pull on the axles- this will impose less stress on the suspension than pulling on the chassis which will ultimately transfer the loads back to the axle via the suspension linkages anyway. The lifting action due to the low angle of pull will also assist the recovery by trying to lift the wheels out of the bog.

However, in a deeper bog where there are suction/drag forces on the chassis/floor pan, applying the load to the chassis may well be a better option if this is the only option available.
