Rust behind head-lights access?

As per title really. I've found the common corrosion behind the headlights, before I start so I know what I'm in for is there access from below or is the rusted area boxed in?

Cheers

Boxed in pal

You need to remove the front wheel arch liner to see the full extent of that.
The good news is it's easy to remove fthe liner, the bad news is that rust will more than likely extend down the rear of the box section. It's double skinned and traps water....and it's the water drain route for the assembly - dumb design.

But if you have a welder it can be fixed...

Daaaaaaammm.

Cheers guys. I do have a welder and metal sheets here so it's not the end of the world. But it is annoying as I already spent some time welding the rear of the vehicle and thought I was about done with the repairs. Ach well. I'll get in about it next weekend

Discovered, as suggested I would, much more corrosion. I think it's terminal for both ends of the slam panel. I'm going to leave it right now I just slapped on a load of rust inhibiting paint to slow it down.

Later this year I'll tackle it. I'm thinking of cutting out the area around the body mount and welding in some new C channel or box section metal.

Pics and info from anyone who has done similar much appreciated

Sorry about that, the rot is always worse than it initially looks in this area.
HOWEVER, keep the faith, it can be fixed.
Lambert got the OEM option in replacement of the complete panel. Someone has done it, if my memory is correct only a few spot welds and an easy fix, approx £300?? --- ask Martin.
Others have made their own in box section to replace the rot, I have seen pictures on this forum, i'll try and find them again for you. This also looked a good end result.
So yep forget it and enjoy the Jimny for a bit, can always be done when u feel like it.

Cheers guys. New replacement panel would be nice and easy but it's for a w plate with a bad paint job so the cost would be hard to justify unless there was no other option.

I came across this solution on the forum. I saved the picture in case I can't find the thread again.

More details (once I refund it I'll ask directly) and similar solutions would be really helpful.

I have a welder and can do patch repairs no problem but I've very little experience with fabrication. Though I'll be giving it a go when the time comes

I've got my years ticket anyway. Fortunately this area is well hidden ...

Here -

Yep that's the one I had seen^^^^^^
Real nice fix and a better design than the original being nice and open, no water or rot traps.

When mine give up that's the option I will go for, you cant see it anyway once all the lights and plastics are fitted, so my pigeon poo welding will not be on show

That fix photo is from forum member 'Kiethy'. Talented fella with everything he touches

Have a look here for a more home-brew approach (for the poorly skilled of the welding world, like me )

Can't believe I missed that one! Tons of handy pics and a great thread to follow. Cheers for that
