Also, I have read that to lift the total front end of the vehicle, one should lift under the crossmember (crossbeam - Jaguar nomenclature?) between the A-arms. I have been lifting at the Reco19 location and putting a block of wood between the crossbrace and crossbeam to avoid distorting the crossbrace.
My Coupe does not have the Crossover Braces.

The Crossmember is under the Radiator as Sam (and JTIS Diagram shows).

The Crossbeam is the Aluminum member between the Front Wheels and is NOT to be used as a Jacking Point.

Reverend Sam thanks for the video. I always wondered how I would jack up my car. This video helped a lot. Thanks!!!

I used the frame as shown in Rev Sam's pics. Structurally it is the only beam that has strength to support 1/2 the car's weight. The x-cross member is fragile and using it could result in it buckling inwards.

I'm glad this finally got hashed out. It seems like the question is raised every few months, and the FAQs weren't very clear. I wasn't even sure if the point I was using was correct, but it seems like the consensus is that the beam below the radiator is the correct spot. Hopefully this will help some people in the future. Just be aware that that plastic piece is going to make a cracking sound. I guess that's normal.

Hello Reverend, and folks

What are the recommended jacking points for a 2-post lift ? All searches so far talk about the OEM emergency jack, and using floor/trolley jacks. These all refer to using the OEM points on the sills, but does the X100 not have better places for the jack pads inboard of the sills when using a 2-post lift ?

I always use the sills jacking points on my lift with extra padding so as not to damage the paint,,,, again.

PS A WARNING TO ALL, REV SAMS VIDEO ON THE REAR JACKING POINT IS WRONG. THE JACK SHOULD GO UNDER THE DIFF NOT THE BRACE BRACKET.

Whoa, this is big news! I know you Race Diagnostics and your advice is always right on the money. So I'm taking it very seriously.

Could you tell us about how you caught this or how it came up for you ?

Thanks, John

Keep in mind the cross bars front and back are associated with the alignment of the car. Any bend or movement of them will affect the drive.

This is only relevant for verts as the area does not exist on coups.

I watched the video before going to jack up my car but then noticed that the area described was very flimsy in the vertical axis needed for jacking the car so checked in the workshop manual which shows the correct position under the diff.

Jacking in the area suggested in the video could result in the collapse of the bracket and bent braces or a lot worse if you are under the car.

It is a real shame that this video is still out there with such a major error as Rev Sam is seen as a real guru and owners will follow his advice without thinking with potentially bad consequences.

The bracket in question is just made out of 20 gauge mild steel with no vertical bracing.

RD, wow thank you. I used that point in the video at least 2x. It'll be the differential from now on. I appreciate the corrections. John
