I'm looking at putting a diif lock in my 2002 hilux IFS and am leaning towards the obvious ARB air locker. does anybody have previous experience with these or other manually operated diff locks? if so i would be very grateful for the feedback.

I would check out the new TJM diff locks (if available for your model) before deciding.They do not use rubber 'O' rings which can give problems when they wear.-Steve

I have a rear air locker from ARB - works well, but had a problem with the seals (O-ring?) which meant a (small) amount of diff oil escaping through the compressor (mounted in my engine bay).

Showed it to ARB, who immediatly booked my vehicle in, and replaced the faulty seal(s).

Would recommend them.

I know a bloke who put a diff lock on a trailer once. I'll ask him if he has any advice.

Have ARB locks at both ends. They take the vehicle to another level. I also had diff oil coming up but it was because of lack of use. It ceased after a few uses and I make sure I use them often now even if not required

TJM make a big deal about rubber O-rings - fact NO arb air locker uses rubber O-rings.
ARB makes over 100 different lockers - TJM makes 2 yes TWO
TJM advertises that their lockers do not require modifications to carrier bearing caps - yes the ARB lockers do on some DANA diffs but on the TWO models TJM compete with ARB lockers only require a single air hole drilled into the housing. The TJM locker instructions have a complete section in the instructions on how to modify the housing with a grinder! Opps did we not mention that in our ad.

Hmm - when ARB worked on mine - I'm not sure if the word "rubber" was mentioned - words were to the effect

"That a seal (or O-ring) was back to front"

when I asked the source of my problem (oil leak from compressor and being pumped out of air - take off from compressor) guess I just assumed rubber.

Work was done in November, hence I'm a bit foggy on the details, especially as I'm not much of a mechanic ! :-)

I have ARB front and rear and can only say good things about it. It has made a very big difference in where I can go and my 4x4 experience

I have ARB airlockers each end of my vehicle and also reckon it has taken my vehicle to another level. I can only say good things about them as well. I believe the o-ring issue is normally related to lack of use and is self rectifying with use and does not effect the operation of the units. This is usually a misting of oil and if oil is actually coming out through the compressor in any qty then the o-ring requires replacing. Do not mount your compressor in the vehicle cabin however as the oil vapour gives off a smell that will annoy the hell out of you. ARB also have a purge valve kit which is cheap and fixes the problem, so maybe getting it fitted in the first place is the way to go. In any case most people don't experience this issue at all.

The TJM units sound good too, however I believe the pricing is no better than ARB units and the range available while being expanded isn't extensive, so check if you can even get them first. My main reason for choosing ARB is that they have been around for Donks and I figured if they were no good, it would be well known.

Whatever you do, go for a locker for sure.

Cheers
