Crossmember

We have 47 Items for Crossmember In-stock.

Rough terrains and rocky trails expose your car's crossmember to high levels of pressure and harsh forces of nature. All these can eventually lead to the deterioration of this car part. You see, a twisted crossmember is not good when it comes to proper handling and smooth driving abilities. The alignment of the body parts or panels may also be badly affected. Because it's a very important structural component, you should take good care of the crossmember for better ground clearance. As soon as you've spotted symptoms of a failing part, bring the car to the garage and have it checked. Replace twisted or worn-out crossmembers with a new one. This car part can be installed on the driver or passenger side, sidemember extension, as well as lower or front location. Look for a new assembly that will be a perfect fit to your old crossmember's attachments. At Auto Parts Warehouse, you can find crossmembers for radiator support and many other applications. You can get them at a much cheaper price compared to other retailers. We also make sure that our customers will get the perfect OE replacements through our 24/7 customer service.

Crossmember Installation for Your Vehicle

The crossmember is an important structural component of your vehicle. They support the underside of your car and carry the weight of the engine and transmission. Installing a crossmember is a lengthy and complex process that requires experience in welding and the use of a blowtorch.

Difficulty level: Difficult

Tools that you'll need:

  • Hydraulic jack
  • Jack stands
  • Blowtorch
  • Welder
  • Wrench
  • Clamps

Note:

The following installation instructions are for 1940-1948 Chevy vehicles.

Step 1: Raise the front of the car with the hydraulic jack and support it with two jack stands. Do the same to the rear. Lift the car high enough for you to work comfortably.

Step 2: Remove the front suspension assembly and the crossmember of the vehicle.

Step 3: Locate the holes in the top and bottom of the frame rails. Make a mark half an inch back from the center of these holes. Make a line from that mark all across the frame. This marks the axle centerline of the new crossmember.

Step 4: Trim off part of the flange in the frame rails with a blowtorch. Trim off 3-3/4 inches of the flange in the front of centreline and 1-7/8 inches at the back.

Step 5: Install the crossmember spacers and the rear spacers in the spacer holes of the crossmember along with their appropriate bushings and nuts. Tighten the nuts and bolts after.

Step 6: Join the rear spacers with the crossmember by welding them together.

Step 7: Weld the crossmember spacers to the crossmember. Try to do so as far as possible into the crossmember.

Step 8: Weld the gussets to the spacers and the crossmember. Remove the bolt after it cools down.

Step 9: Fit the crossmember onto the frame of the car. Use the axle center line to properly align both of them. If the crossmember does not fit, you will need to grind the sides of the crossmember until it does.

Step 10: Spot weld the crossmember to hold it in place then weld the whole thing completely.

Step 11: Place the spring towers on top of the frame rails. The front of the tower should be about 1-3/4 inches forward from the crossmember.

Step 12: Clamp the spring towers in place then weld into place.

Step 13: Install the stock strut rod if necessary. This will usually depend on the crossmember you've purchased.

Step 13: Install the steering rack.

Step 13: Reassemble the rest of the vehicle.
