4x4 Not working

The 4 wheel drive has packed up on my jimny When I looked the vac pipes on the front axle had snapped, I checked price of a new one from dealer £106 and this needed ordering in so I made up a new one with brake pipe & tee connectors fitted it and it's not working? Can anyone tell me how the hubs work and how to check them, also the correct way the pipes go on, maybe a diagram if pos or a site that may help, I am quite sure I have them the right way as I was careful when I removed the old pipe.

I know every one reccomends fitting manual hubs but I believe you need to modify the hubs and I need the 4x4 working ASAP as we still have snow.

thanks in advances if you can help...........

take your hubs off and activate them yourself, pop a finger inside and push, the gear ring will pop into place, fit back on jimny and you have locked hubs, select 4 wheel drive as normal and away you go.

alternatively, the sj ones are easy to fit, infact its a 10 min job

Martin has a spacer kit in his shop section, with this the sj hubs a a straight swap

Hi and welcome to the forums.

I have written a guide to problem solving on the Vacuum Hubs

see HERE

When you get tired of working on them get yourself a set of SJ manual hubs and buy some bolt on adaptor rings from my favourite on-line shop

Thanks for the quick reply, I will have a go at repairing the vacuum problem and will look out for hubs in my local breakers yard. Is it only SJ that fit as I know he has a Vitara in?

vitara ones will fit as well,

if you go down the manual hubs route i would suggest soaking them in diesel for a couple of days go give then a clean and keep the operational via hand, ie when you get out to lock your hubs they turn easly by hand, after a couple of days regrease and fit if you are ready to fit them.

Called to breakers yard he had a 410 in with fixed hubs are the free wheeling hubs a after market thing or did early 410s have the fixed type?
