^^^ I'm confused. Are you talking about the actual pinch weld or the liner. You really shouldn't just cut the pinch weld metal back to the fire wall. The cuts are supposed to be made perpendicular to the "fin", every couple inches (between the spot welds) and hammered over flat.

No - it really doesn't.

As far as eliminating tire rub, sure, but if you cut the entire pinch weld out then you just compromised the integrity of that portion of the unibody.

Either way you can still weld it back together, it's not a big deal plus you get more tire clearance

Right - which is why I asked if you rewelded the seam. It IS a big deal if you don't reweld it.

It's not cut deep enough to separate. And it was heated and flattened together

Seriously, if you cut the pinch seam out past the spot welds it isn't being held together by anything anymore. That's what the spot welds are for. Using heat and flattening it together isn't going to do anything. It has to be rewelded - plain and simple.

There is a reason the pinch weld modification is done the way I linked in my post above. Any of the unibody platforms that are typically modded, which is all the Cherokees - XJ, ZJ, WJ, WK; the Commander - XK; the Liberty - KJ, KK - they all have a pinch seam and when that pinch seam is modified to fit bigger tires you can't just cut the entire thing out unless you plan to reweld the edge of the seam where you cut it. This entails much more work, not to mention a welder and welding skills - which not everyone has. Which is why the modification is done making cuts between the spot welds and hammered over.

Otherwise the unibody is weakened.

While its only a DD and rarely off road, if ever....the pinch weld hold the unibody together and essentially works to hold hold it all together regardless of what type of driving you so. A bump, or sharp turn puts stress on that area, thus the pinch weld. If you didn't hit it with some Rustoleum either, it could get ugly quickly for you if in a colder climate that uses salt in the winter. If the weld was only needed for off-roading, it would be a mod people ADDED. It comes with the PW from the factory for a reason.

Sal isn't going to touch it with the liner over it, I'm getting it welded anyways just in case.

Splashing slush with salt in it can do damage too over time. Good idea getting it welded. The liner looks good!
