Jacking up axle with diff guard fitted
So I have wrap around diff guards fitted on the front a rear.

Normally, you can lift the vehicle with a jack under the diff bump, but is this safe to do with a diff guard fitted? Could it take the load? There's not much space on the drivers side to get a jack and axle stand in.

I'm leaning towards a no but wanted to check.

I wouldn't risk it, they are designed for limited impact and not weight / load.
Sound like a situation where you could do with a hi lift to then carefully put axle stand under.
If you need the axle to lift with the body and chassis then before jacking use a ratchet strap.
I assume this is the issue your having? ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️

What brand do you have?

I have been putting jacks under the QT / Wildbear diff guards for years with no i'll effects. They are that well designed to cope with it.

I have put the jack under my QT diff guards with no problems. I'd hope the guards are stronger than the diff they are protecting otherwise I would take them off.

Not sure of the brand - they came from the big stall at Peterborough last year which was all suspensions struts, chequer plate, diff and steering guards.

The steel is very thick, especially when looked at next to the metal my 3 ton trolley jack is made of so I did always wonder if it was doable. I'm never lifting it too high and always then lower onto axle stands before working on anything.

I normally try to avoid using the diff as a jacking point, preferring the suspension mounting points. It's too easy on a normal diff, without a guard, to damage the very thin diff cover and it's not really a stable jacking point.

That said, if a diff guard isn't strong enough to jack the vehicle up then it needs binning, in "normal" use a diff guard may well end up taking the weight of the vehicle when it's doing it's job. http://www.yorkshireoffroadclub.net/

I use a Sealey cross beam adapter on my trolley jack, this makes sure you are lifting evenly across the axle and avoiding the diff guard. https://www.bodyshop-tools-supplies.co.uk/...0wod4OwJpQ
