Freeing up low range

1st attempt - Lots of WD40 sprayed at linkage from underneath vehicle.
2nd attempt - remove cabin transfer gear boot and spray with lots of WD40!!
Worked for me in 2003 and have been through lots of dust and water since without return of problem.

Yeah, I find mine is especially hard to get in at around the 110km/h mark....;-)

But seriously...They've got bugger all leverage / mechanical advantage. I was toying with making up an extension for the lever on my 75. When I was doing exploration, we'd drive them 'Mack twin-stick' style, shifting on the fly with the left hand changing gears, right arm through steering wheel and swapping from Low 5th to High 3rd on the go.

If the 79's always on-site in 4WD, a bit of transmission 'windup' may be your problem going from H to L. Try reversing backwards for a bit to see if it's an external (seized, mud) or internal(windup/fault) issue. Better still, go 2wd, stop, select 4H then 4L.

A thought I had just this week, after playing in lots of mud on the weekend, was to simply cable tie a couple of lengths of garden hose from the edge of the tray to the transmission tunnel area for a quick 'de-mud' spray when I get home. Just click on the hose and have a beer until the water is coming out clean. The bash plates on mine mean the only other way I can get to clean this area is to lie in muddy water under the vehcicle and get covered in crud. Very boring.

This would cost under $10 to make and keep the linkages, shafts clean(er).

Yep they r a mongrel to get in gear when there not used much.

Try a hydraulic ram and if that doesn’t work then swear and call it names. It won’t make it work but you will feel better. :)

See if you had electronic 4WD selection you wouldn’t be having this sort of problem.

Instead light’s would be flashing at you and it would be making buzzing and clicking sound’s:)

Usually it is the detent ball with a bit of water..... goes to crap. not hard to whip them out and give them a clean. Never done one with oil in the case though can't say if they would leak oil, I would imagine they do.

I'll go and have a squizz and let you know

this happened to my wheels too. After pulling everything apart and thinking we fixed it I also sought advice form this forum.
CRC did the trick and I give it a regular dose every month or so now.
