Bought this viscous coupling (center differential) to replace my current one. The fit was perfect. The new part rid the car of its shuddering/clunking/hopping feeling that was occuring after 20-30 min's of driving. When turning at low speeds, the car would shudder and make a loud clunk type of sound, sometimes feeling like it was skipping. This was caused by torque bind and replacing the center differential corrected this. Pleased with the part.
