4 WD Not engaging.

[11redrex]

Had to use it in anger for the first time today and the bloody thing wouldn't go into 4wd. It has always engaged in the past, got half way up a very slippery slope this morning and it started to spin the rear tyres, but neither of the fronts were doing anything. Backed it out and went a different way. Got it stuck again about half an hour later (on the flat !) and again it wouldn't engage the front wheels.
Any common causes I should be looking for ?

i had it where 1 was locking but the other wasnt which removed the drive to both wheels

Had the same problem stripped both hubs and found that on of the springs had broken. Replaced cost £3.75p. Works now

Told you they are unreliable Karl... you'll find when auto hubs are not used often, when you come to really need them they fail.

On with the manuals :thumbs

Not allways the best solution but I have to say I've had no problem's since fitting the manuals but if we bang on about Manuals Plank will join in:lol I think the later models with fixed hubs were the best solution but they must drop your MPG. I can feel a difference when my manuals are locked but I lock mine when I'm likely to need 4wd and every month or so just to keep the transmission free running.

Load's of threads and a few downloads about hubs.

I find folk who use their motor as a road car will argue autos are better... anyone who is a regular off roader will argue otherwise, myself... I base my opinion on my own experience, i've had 2 sets fail when I really needed them, Karls had a set fail, Redrex has had a set fail and tons of members of the other forum have had them fail...
So my advise to anyone who has a set fail, dont repair them buy a second hand set of manuals, will save you time and effort next time they fail

 

[11redrex]

Anyone got a set of manual hubs for sale ?

 

[jims-terrano]

I got mine from Milners back when they were 55 quid each. I reckon they'll be like hen's teeth.

Not cheap but maybe these:

Or as Jim suggested:

£62 each aint too bad. I'll be getting 2 from milners soon.

Hit Ebay, make a list of all the breakers advertising and get ringing round! There is one guy on there with like 30 Mavs and Terranos in his yard, if he dont have a set i'll eat my hat

When did you get the spring from? Cheers

Well I'm still waiting for someone to tell me how they get busted when they aren't part of the drivetrain......:nenau

Got the spring from my local factors. Will get the part number. He had no problem. I just showed him what I wanted from the manual and he ordered.

reading some other threads on here it looks like it could be :
a lack of grease (not me),
setting off too quickly in 4wd (could be me) or,
rebuilding one of them wrongly after fitting the cv boot (almost certainly me).

The cv boot came off again so I'll have it all to bits later, maybe I'll put it back together properly this time :augie

Still searching for manual hubs, most of the breakers on ebay just look way too dodgy to buy from, plus they don;t know the difference between a manual and auto locking hub. One of them told me the auto didn't have locking hubs. :doh

She's alive !! Took the hub to bits, gave it a clean, put it back together properly, and went looking for a place to play. The one decent bit of ground near here got gated off years ago but I was pleasantly surprised to find the gate was open tonight. Didn't get up the 60% slope but the 4wd is definitely working !! whoop whoop.

The brake set things look a bit worn on the edges, should they be perfectly square on the corners ?

How simple is that hub design ? I was amazed that it's really just a very thin piece of bent metal that makes it work. And why would anyone change to manual hubs when these do exactly the same thing without having to get out ? Mental.

I agree with you, mostly because I couldn't fit manuals anyway, with my alloys, couldn't get in to change them over.:nenau

Exactly, and that bit of metal isn't part of the drivetrain as I said; its only doing anything at the exact moment of engagement/disengagement - apart from that its not under any strain at all, so a puzzle how it gets busted unless its just old age and fatigue - oh sorry thats me....

after taking mine apart i have noticed how simple it is mine had a bent spring so it wouldn't engage the 2 little light that poke out the side is what threw me till i realized that's what moved to extend the hub in to the locking threads :thumb2

i guess as the spring gets old it looses it springyness and just bends or snaps

but its the brake ring that throws me how does that stop the plate in place when its covered in grease :nenau
