Ok. Been almost 25 years since had a vehicle that used stupid pinch-welds jackpoints.
Didn't think about it when purchased CX-5 vehicle.
Anyways, usually try to lift with floor jack by crossmembers or pumpkin but that's not always possible.
Learned more about pinch-welds.
Appears they are spot-weld at factory then an adhesive is melted along the welds to fill in any gaps.
No wonder these areas rust out so easily. Just one more reason to use Fluid film on the vehicle and coat the rockers and pinch-welds liberally. Might have to go out and fluid film them again today. Careful jacking of the welds is also best to avoid any damage or bending which would allow water intrusion
I need to use the pinch-welds for jackstands placement, emergency jacking or when my garage is full(which it is full until spring, thus not able to use my floorjack). Therefore am looking at everything as far as pinchweld points.
The Mazda supplied scissor jack does not touch or lift the pinch-weld itself but the wide area of the jack contacts and lifts the car by the inner flat portion of the weld while every single jack pad sold is meant to lift by pushing on the vertical pinch-weld as the slits are only 0.5 inches deep.
My hockey pucks are too thin so a store-bought jack pad of 1.3 inches thick is needed. By using a saw to deepen the slits to 0.65 to 0.75 inches should allow the pad to contact the cx-5 flat inner area for proper support. The jack pads are more expensive than hockey pucks but imo, the extra thickness is needed.
Pucks still used for pumpkin and crossmember lifts but think the thicker jack pads are needed for the pinch-welds and should work great once modified with deeper slits to possibly place on bottlejack.
Has no one run into this issue yet with the pinch-welds? Are you all modifying your pucks?
Also have to wonder if Mazda designed the scissor jack to lift by the inner flat area but
then the garages use 2-post lifts to lift vehicle by directly under the vertical pinchwelds, is it damaging the welds ???
Maybe it's opening up the gaps in the welds ever so slightly ? thus all the more reason to fluid film the welds thoroughly.
