Rear Jack Location

The owner's manual indicates the jack location and states that the jack pad must span two crossmember ribs. However, the crossmember ribs at the control arm pivot point locations are not level or even close to level. The rib on the front side of the pivot point is 5/8" higher than the rib on the back side of the pivot point.

Should I make a wooden wedge to install between the jack and the crossmember, or is one rib adequate?

The way I did it was use a 2x6 with small 2x6's cut for the ended making a u shape so weight was towards the sides while lifting in the center

You can use a board but I'd suggest using the Northern Tool adaptor beam with a quality floor jack. Here are some links that may help.

Modifying Northern tool support beam for use on Craftsmen floor jack:

(This is a simple and worthwhile modification allowing the adapator beam to be fully and safely seated on the jack. If you want the images with this thread, PM me...I have them).

I have a support beam similar to the northern tool beam with a Sears 2 ton aluminum jack. But when the jack is raised to contact the cross member, the pad only contacts the rib on the rear side of the control arm pivot point as the rib on the front side is 5/8" higher.

When I first bought the C6, I ordered the part from Northern but it was on back order. So being a woodworker, I made a part from a 4x4, with the proper angle to accommodate the diffence that you mention. Works great. BTW I also have wooden ramps to drive up on, and wooden blocks to put under the rear wheels while I am doing the actual oil change.

Wayne is right, the Northern Tool cross beam adapter is the way to go.

Modifying it to your jack can be a project though. Luckily I have a tool room at my disposale.

I had to fit mine to my Omega low profile jack and I have to tell ya it works great. I attached some rubber pads to the center piece for when I use it on the front end since you cannot use the extension pads there.
