How to Replace a Subaru Legacy Crossmember

A crossmember is deceptively simple in appearance. But it’s actually a complex piece of engineering that supports your engine and transmission, and reinforces your chassis. A bent crossmember may seem like a minor issue, but it’s actually a big deal.

What Happens When a Bent Crossmember is Not Replaced Right Away

Legacy crossmember

When you have a bent crossmember (even one that’s slightly bent) on your Subaru Legacy, its structural integrity is compromised. Other problems will also arise, such as:

  • Poor wheel alignment
  • Bent suspension components
  • Misaligned transaxle

The best way to prevent the above issues from cropping up is to diagnose a bent crossmember and then replace it straight away.

What if a Crossmember Replacement Isn’t in Your Budget?

A crossmember replacement at a Subaru dealership can run you several hundred or a thousand dollars because:

  1. Dealers impose a 30% markup (give or take) on replacement crossmembers.
  2. Labor costs $100 per hour or more.

A bent crossmember is one of those issues that will cause more damage the longer it remains on your car. If you act quickly, you can avoid a huge repair bill that involves fixing or replacing affected parts. It’s in your wallet's best interests to replace your crossmember as soon as possible.

The good news is you don’t have to take out a second mortgage to get your crossmember replaced. You can definitely swap it out at home as long as you have a reliable car lift and this handy tutorial.

Replacing Your Legacy’s Crossmember in 9 Steps

Take the following steps to replace the crossmember on your Legacy in the quickest, most efficient way possible:

  1. Buy an OEM replacement crossmember.
  2. Lift your car in a way that’s safe for you to work underneath it.
  3. Disconnect the control arms.
  4. Remove all of the bolts connecting the crossmember to the car frame.
  5. Take out the old crossmember. (You can try to remove the crossmember by maneuvering it out over the differential. On some cars, you will have to remove the differential.)
  6. Put in the new crossmember. Use a jack to hold it up or rest it on the differential if it’s still bolted in place.
  7. Reconnect the control arms. Be sure to use factory torque specifications.
  8. Reinstall the differential (if applicable).
  9. Inspect the crossmember to see if it’s straight using the steps listed here.
