Buick shares its platforms with other GM brands — LaCrosse and Lucerne with Impala and DTS, Enclave with Traverse and Acadia, Encore with Chevrolet Trax — but Buick trims add their own lighting, trim and suspension packages. A large share of the Buick parts we quote are for 1995–2011 LeSabre, Park Avenue, Century and LaCrosse with the 3.8-liter V6, plus classics from the 1960s and 1970s, so year and engine drive the fitment.
What’s different about Buick drivetrain and exhaust parts
- Front-drive Buicks use CV axles that differ between the 4T65-E and later 6-speed transmissions, and the intermediate shaft on 3.8 V6 cars is a separate part; Enclave AWD adds a rear differential module and driveshaft shared with Traverse and Acadia.
- Catalytic converters on the 3800 V6 are single units, while the 3.6 V6 uses close-coupled converters built into each exhaust manifold; California-emissions cars need CARB-certified units.
- Engine and transmission mounts on LaCrosse, Enclave and Encore are hydraulic and collapse with age, and the shifter cable bushings on 2010+ models are a well-known failure; classic rear-drive Buicks use a driveshaft with U-joints sized by wheelbase.
