Does anyone have experience in repairing the sub frames on an E-Type? In the course of my restoration I've discovered rust in the top rail on the passenger side sub frame. I believe it can be cut out and replaced but I don't know what type steel Jaguar used in the first place. Can anyone help with some information?
Thanks in advance

Dave,

I strongly agree with Pascal and Chuck. Do NOT try to repair the frame rails. They MUST be replaced with new ones or used ones that you are certain are in excellent condition. All of the stresses of the suspension and the weight of the engine are carried by those rails. You don't want to be cruising along at 70 or 80 or 100 mph and find out that the repair you had done was not going to hold up. Replacement rails are readily available from multiple sources and are not prohibitively expensive.

Just bite the bullet and replace them. You'll be glad you did. And remember, like most other parts of an E-type, these things will rust from the inside out. So if you're seeing rust damage that's eaten through, chances are a good portion of the frames are already dust.

Dave;

I agree with Pascal, don't take a chance-replace at least your passenger side rail, but preferably all of them for safety and peace of mind.

no... it's a special alloy which can not be welded, only brazed. is that the only spot? check carefully near the battery or anywhere moisture can get trapped. usually, they rust from the inside out... shake them around to see if you hear loose chunks inside.

new frames are available and compared to the cost of a restauration, it's not worth trying to save a few $ on these. Even if you have someone who could braze the right metal, it will become an issue if you sell the car.

the rails hold the engine AND the front suspension... dont' take chances.
