Do I need to replace struts in pairs?

Yes, struts should always be replaced in pairs (both front or both rear) to maintain balanced handling and ride quality. Compatible vehicles include 2007-2010 Cadillac STS and more. Uneven strut wear causes pulling, uneven tire wear, and compromised safety.

Is wheel alignment required after strut replacement?

Absolutely. Strut replacement affects suspension geometry. Without alignment, you risk rapid tire wear and poor handling. Most shops include alignment with strut installation.

Is this part covered by warranty?

Yes, this ARNOTT Suspension Strut includes a 24-month limited warranty covering defects in materials and workmanship. AutoBuffy also offers 30-day hassle-free returns if the part doesn't fit your vehicle.
