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 1991-1995 Toyota MR2 and more. Uneven strut wear causes pulling, uneven tire wear, and compromised safety.

Is wheel alignment required after strut replacement?
