Cheap Mercedes-Benz GLS CV Joints

Yes, the GLS is a permanent four-wheel-drive SUV across all generations, so it has CV joints on both the front driveshafts and at the transfer-case end of the rear driveshafts. All variants – petrol, diesel, and AMG – share this layout, so CV joints are a genuine part on every GLS built. If you are unsure whether you need the inner or outer joint, or the driveshaft assembly itself, confirm with the breaker against your registration.

The X166 and X167 are different platform generations and the driveshaft and CV joint dimensions changed between them, so these parts are not expected to interchange. Name the generation boundary to your breaker – supply your registration and they can match the correct X166 or X167 unit. Never assume a cross-generation part will fit without the breaker confirming it against your VIN.

It can do – larger or higher-output engines (for example the GLS 580 V8 or AMG GLS 63) can put significantly more torque through the driveshafts than a GLS 300d or 400d, and Mercedes sometimes specifies a heavier-duty joint or driveshaft assembly for those variants. Always tell the breaker your exact engine code and model designation, not just the year, so they can match the correct rating. Fitting an undersized unit from a lower-output variant is a risk not worth taking.

Yes, this matters – left and right driveshafts on the GLS are different lengths and the CV joints are handed accordingly, so always specify nearside (left, kerb side) or offside (right, driver's side) when asking a breaker for a quote. If you are unsure which side has failed, a good indication is which side clicks or vibrates under load. Getting the side wrong means the part simply will not fit.

Trim level on its own does not affect CV joint fitment – AMG Line is primarily a cosmetic and suspension-tuning package and does not change the driveshaft or CV joint specification. What does matter is the engine variant, so a GLS 580 AMG Line and a GLS 400d AMG Line would not necessarily share the same joints. Ignore the trim name when searching and focus on the engine designation and generation instead.

The GLE (W166 or W167) and GLS share platform architecture and some running gear, so there is a possibility of overlap on certain variants, but this is not guaranteed and should not be assumed. Wheelbase, weight, and powertrain differences between the GLE and GLS mean the driveshaft specifications can differ even on similarly badged engine variants. Confirm any potential cross-model substitution directly with the breaker using both registrations before purchasing.
