1988 90 - Rear Crossmember Steel Thickness

Does anyone know off-hand how thick the steel is on the rear cross-member?

Gotta repair a couple of patches, and might pop to a fabrication shop for some scraps on the way home from work

Cheers. Tom.

go for 3mm

I've got plenty of 3mm plate, so I'll go with that

Ok, I think the original thickness is 2mm, so I'm going to go with that.

When welding, do you just disconnect the battery, and leave the alternator connected? I wonder if it's a good thing to leave the alternator earthed or not.

The original thickness is 2mm.... I just had a 3mm heavy duty rear xmember fitted to replace the original 2mm on my 1994 Defender. I know jack sh*t about welding but from previous posts I have read.... if using a MIG, disconnect the ECUs, alternator and battery to avoid damage. Maybe a wiser member will confirm? Don't want you to damage you pride and joy.

well, I'll be using my stick welder most likely, although I do have a MIG I'll disconnect the alternator. It's just that there are arguments about whether its better to leave it plugged in, but I'll disconnect, and might even remove it from the vehicle, as I need to modify the hole for the tensioner bolt anyway

Don't know about ECU's but we just disconnected the batteries on the farm. You only need to disconnect one cable though and I can't for the life of me remember.

where is the ECU located in the OPs landy ?
