Hey everyone,

back with something a little different this time—today it’s not about the HJ60, but rather my brother’s 1999 Land Cruiser 100 Series, which serves as his daily driver and workhorse. It’s sitting at 279,000 km and still runs strong, but, well… let’s just say the body and frame are starting to show what two decades (and some questionable repairs) can do.

The second picture already tells part of the story:
* The right quarter panel is pretty much gone.
* The left quarter has patchwork welded all over it—spaced out welds every few inches and some seriously rough metalwork.
* Same story on the left wheel arch, where things were just tacked together.

These repairs were all done previously in Serbia by the former owner—let’s just say they were more about keeping it together than making it right.
But the real concern is underneath:

The left rear frame section, right where the last body mount sits, had a huge rust hole. We knew it needed attention, especially since these frames are known to crack in the rear when towing or under stress. Since it’s a frame-on restoration we had to get clever (used for daily business and we only have limited time to fix it)

We started by removing the body mount to get full access, and yeah… the damage was worse than expected. Once open, it was obvious: the surrounding frame was incredibly thin, less than 1 mm thick in some spots, where it should be closer to 3 mm. The rust was hiding behind every layer.

So what’s next?
We’re now working on fabricating a strengthening piece to rebuild the bottom and outer wall of the frame. Afterwards we will fit a new outer part.

Also, once the critical frame repair is done, we’ll move on to fixing the remaining smaller issues around the body—like the quarter panels, wheel arches, and any questionable welds we come across. One step at a time, but the plan is to make this daily a reliable rig again.
Thanks for reading, more updates coming soon!

wow, thats crazy how thin the metal became over time. Good luck on this repair, usually 100s do not rust this badly
Unfortunately that's pretty normal in Austria. (Heavily salted in the winter). They tend to even break when hauling heavy equipment.
 
Nice work @WRNG Lifestyle!
The 100 is not very resistant to rust. They need regular and thorough cleaning to keep the old tin worm away. I've seen several in Scandinavia that look like Swiss cheese!

Looking forward to future updates.
 
Hey guys, hope you’re all doing great!
We’re back with a fresh update on the 100 Series and — surprise, surprise — the deeper we dig, the more crust we find. 😅

This time I decided to inspect the inner frame where the spare tire mount attaches, and yeah… there wasn’t much left. So, as expected, I cut it open and rebuilt to the needed thickness. That part actually went pretty well.

Now onto the real problem zone — the bottom layer of the frame where the trailer hitch mounts. That thing was paper thin, barely 1 mm of metal left in spots. So I fabricated a reinforcement plate, roughly 36 cm (about 14 inches) long, to give the area some real backbone.

To make sure this thing holds more than just hope, I drilled multiple holes for the plug welds to fully attach the plate to the backside of the frame — not just the sides. It’s now completely locked in, giving us a much stronger base.
When the outer layer goes on, both pieces together will give us a solid 8 mm of steel (~3.1 inches) in total thickness. That’s more than enough to support the hitch and any towing work ahead. And of course rust protection was added on every piece.

Side note:

If the rust had crept closer to the suspension mounts (like what we dealt with on the HJ60), I would've made the reinforcement even larger to spread the stress over a bigger area. But since we caught it just in time, this solution should do the trick.
Also attached a quick pic showing how the new piece is going to sit in place 👇
Next step: burn in all those plug welds, fit the outer layer, and reinstall the body mount so we can get this corner buttoned up for good.

BR,

Nice work! Glad to see someone doing rust repairs on these - we're in the UK and our roads are also salted heavily so we will undoubtedly be doing similar work at some point down the line.

Unfortunately yes! But there's nothing that can't be saved
