Rear axle beam replacement
The rear beam maintains rear-wheel geometry and, on many vehicles, cannot be repaired once bent.
Symptoms
- The car pulls to one side, rear tires wear unevenly on the inner edge, alignment angles won't hold spec.
What's included
- It is replaced after an impact, for perforating corrosion or when bush seats are damaged and restoration is uneconomical. Signs include pulling to one side, inner-edge rear-tyre wear and wheel angles that cannot be set to specification. Before recommending replacement, we check beam geometry and compare both sides’ angles: pressing in new bushes is sometimes sufficient. Rear-axle alignment is mandatory after fitting a new beam.
Additional checks
- Checking the condition of the bushing seats
- Assessing whether restoration is economically justified versus replacement
Why it matters
Both sides' angles are compared before replacement is suggested — sometimes re-pressing the bushings is enough. On many cars a deformed beam simply can't be repaired.
More details
The rear axle beam sets the geometry of the rear wheels, and on many cars it's a non-repairable part once deformed. It's replaced after an impact, in case of through-corrosion, or when the bushing mounting points have failed and restoration isn't economical. Signs of a problem include the car pulling to one side, the rear tires wearing on the inner edge, and the angles refusing to hold spec. We check the beam's geometry and compare the angles on both sides before proposing a replacement — sometimes pressing in new bushings is enough. After installing a new beam, a rear-axle wheel alignment is mandatory.
