REAR CROSSMEMBER

A known weakspot of the Scoprion design is the rear crossmember. It is underdesigned and prone to cracking. No worries - it only supports the engine/transaxle and the rear suspension arms! This car had suffered this failure when I bought it and repairing it was job one.

  • This shows the condition of the crossmember when I purchased the car. The seller submitted this photo before I purchased so I knew that a repair was in order.
  • When removed from the car, the extent of the failure was clear - it was cracked thru on three sides.
  • Notice the cancerous growth on the face of the crossmember - an earlier "repair". This had to go.
  • REPAIR

  • The first step of the repair was to remove the cancerous growth, clean the inside of the crossmember and treat with rust inhibitor, and weld the split back together.
  • To stiffen the crossmember and avoid further failures, I made a sheet metal panel to add another "box" to the crossection. This increased the bending stiffness of the section. The sheet metal panel was welded in place.
  • This is the sheet metal panel tacked in place before welding completely.
  • The repaired piece was finished by painting with corrosion resistant paint.

    MOTOR MOUNTS

  • In the process of re-installing the crossmember, new motor mounts were installed all around.
