Mercedes-Benz SL CV Joints Replacement Parts

The Mercedes-Benz SL is a rear-wheel-drive car throughout all of its generations, so it does not use CV joints in the conventional sense found on front-wheel-drive or four-wheel-drive vehicles. The rear-wheel-drive layout uses a propshaft and rear driveshafts with universal joints (UJs) or flex discs rather than CV joints at the front axle. If you are hearing a clicking or knocking noise associated with drive, you are most likely looking for rear driveshaft components, a flex disc (guibo), or a propshaft centre bearing instead. Speak to a breaker about exactly which drivetrain component you need, describing your symptoms, and they can identify the correct part against your registration.

It is quite possible, as some mechanics use 'CV joint' loosely to describe any constant-velocity style joint, and later SL models do use CV-style joints on the rear driveshafts rather than traditional UJs. If your SL is from the R230 generation (2001–2011) or R231 generation (2012–2022), the rear driveshafts may indeed incorporate CV-type joints, so it is worth clarifying with your mechanic exactly which joint and which end of which shaft is affected. Ask them to confirm whether it is the inboard or outboard joint, and on which side (NS or OS), before approaching a breaker. Confirm the exact component description against your registration when getting quotes.

The R230 SL ran from 2001 to 2011, and within that generation there were engine variants including the SL350, SL500, SL55 AMG, SL600, and SL65 AMG, and driveshaft components can differ between these due to differing power and torque outputs. Parts from the same engine variant within the R230 generation are more likely to be compatible than parts crossing between, for example, a standard SL350 and an SL55 AMG. Always confirm the exact part against your registration and the donor vehicle's registration with the breaker before purchasing. Never assume fitment based on generation alone without checking engine variant.

The R231 replaced the R230 in 2012 and is a substantially different car with a different platform, so rear driveshaft components from an R230 (2001–2011) are very unlikely to be compatible with an R231 (2012–2022). Always treat the generation boundary as a hard stop and source parts from the correct generation. Confirm the specific part number against your registration with the breaker to be certain.

On the SL, trim level in the cosmetic sense does not affect driveshaft joint fitment, but the engine variant absolutely does — an SL500 or SL55 AMG will have driveshaft components rated for greater torque than an SL350, and these are not necessarily interchangeable. Treat the engine designation (350, 500, 55 AMG, 600, 65 AMG) as the critical fitment factor rather than any trim or equipment pack. Always confirm the correct part against both your registration and the breaker's donor vehicle registration before buying.

Rather than searching for 'CV joints,' you are likely to have better results searching for 'SL rear driveshaft,' 'SL driveshaft inner joint,' 'SL driveshaft outer joint,' 'flex disc,' or 'propshaft centre bearing,' depending on which component your mechanic has identified as faulty. Describing your symptoms — such as clicking on acceleration or vibration at speed — to the breaker will also help them identify the right part. Always quote your exact registration so the breaker can confirm fitment against the correct generation and engine variant.
