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 2006-2011 Mercedes-Benz ML350, ML500, ML550 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.
