It goes under the transmission and has a nice flat surface that makes an excellent platform for lifting. I have lifted the rear of the 928, entirely off the ground using the cross member, with no problems. In the front of the car there are a few places where a 928 can be supported by jack-stands. Assuming the car is lifted at the lift points (so those will not be available) the car can be supported on the lower control arm rear support bracket, or the frame foreward of the crumple zone. That location is where two frame members are welded together to form a seam. As you go rearward, the seam disappears, that's the crumple zone, do not lift there or further back from there. (Personally, if I'm not going to do any work on the suspension, I put the jack stands on the lower control arm rear supports. Since the bracket is curved, I only put a piece of leather between it and the jack stand (to keep the steel of the stand from marring the aluminum of the bracket). YMMV.

I use the rear support for the lower control ar up front, and in the rear I use the flat plate inboard of the jacking pad. There are other locations, but these should be relatively easy to locate and use. YMMV. ~Merry motoring~ From: Wally Plumley [wplumley@bellsouth.net] Sent: Monday, December 04, 2000 9:51 PM To: 928 Subject: [928] Re: best place for jackstands(on car!)

Any suggestions (regarding the jack points) would be >appreciated. thanks, Jim Morehouse '82 5 spd 1) Place floor jack under rear jack point, jack car. 2) Place jack stand under front jack point. Place block under rear tire. Carefully lower floor jack. 3) Place floor jack under other rear jack point, jack car. 4) Place jack stand under front jack point. Place block under rear tire. Carefully lower jack. 5) Place jack under rear cross-member - Use care to ensure that jack is centered and is NOT on differential or transmission. 6) Jack car. Place jack stands under both rear jack points. The "block" referred to can be made by stacking three or four layers of 2" x 12" x 16" lumber, nailed/screwed and glued, then adding a 2" x 2" x 11" stop on top at each end. Final result should be a very strong, stable support that will hold the car 4 1/2" (three layers) or 6" (four layers) higher than normal, with virtually no danger of falling or rolling off. You can use a jack stand at step 2) and step 4) to hold the rear high enough to get the jack under the rear cross-member, but it is not as safe. Don't be tempted to place a jack or a jack stand under what look like frame rails behind the front wheels. These are thin sheet metal stiffeners, and will bend instantly.

The car can be supported up front by either a jack or a stand at the following locations. The jacking points, the frame where two panels come together (you'll see the seam that is formed by their union), the rear lower control-arm support (where the height tab is located), the front lowere control-arm support, and the tow hooks in front of the lower control-arm front supports. In the rear, the jacing point, the plate just behind it, and the cross member below the tranny (make sure you hit that dead center). In all cases, use a piece of wood between the jack or stand and the metal on the car. Caution, do not try to support the car on what appear to be frame rails. These are the box-like pieces that run front to back and easily seen just under the driver and passenger seats. They are NOT structural. Just in front of the passenger area, they are formed by two panels, and form a seam. It is safe to support the car from that part of the frame rail. This topic has been discussed at every 928 Frenzy. It is very likely to be mentioned again at the next one. Hope to see many of you there. ~ Merry motoring ~
