how concerned would you be

[Connaught]

was out in the sand dunes the other day, and on the beach in 4 lo, after a couple hours and some bbq diner, later at a rather inopportune time i wanted 4 hi, so i stopped, switched the switch, waited and watched the indicator flash, went fwd, reverse, stop switch 4lo to 4 hi,..... this went on a bit, you get the idea, it was stuck in 4lo,

that however is not the concern, (i, after some reading, believe it was a sticky actuator as i don't use 4lo that often)

the concern is the rather significant 'thump' with and undertone of 'bang' that went along with the transfer case finally switching to 4 hi, admitedly i was under power and attempting to accelerate at that point, which is a less then ideal point to switch over,

how tough is the transfer case, will occasional unintentional abuse break it?

the box seems to work fine now, i am wondering if this is like the time i engaged 4hi from 2 hi while steering through a corner by mistake(that doesn't sound nice either)

have a look under the car check your front diff isn't pissing out oil, they like to break, never heard of the transfer case breaking though.

I've not heard of a transfer case breaking, but most of us stop the vehicle before changing from 4LO to 4HI or vice versa - since you need to be in neutral and on the footbrake when engaging 4LO, changing from HI to LO or LO to HI when fully stopped becomes second nature.

Personally I wouldn't change on the move. The transfer case is supposed to handle some strain, but that's once it's engaged. In changing the ratio, you're asking gears to mesh/unmesh and that's when they're most vulnerable.

A slight thump when 4LO is engaged/disengaged should be expected. More than that and you might be looking at a different problem - but you could always get underneath while someone engages and disengages while you have a listen. I don't think the engine needs to be running, but even if it does, you can leave it in neutral.
