MG4 Front Ball Joint
This MG4 front ball joint is the pivot that connects the control arm to the wheel hub, letting the wheel move up and down and steer at the same time. Electric cars are heavy, which puts extra load on suspension joints like this one.
Specifications at a glance: cone size, small 16 mm, cone size, large 20 mm and outside thread M12 x 1.5.
Signs Your Front Ball Joint Needs Replacing
Signs of a worn ball joint include a knocking or clunking noise over bumps, vague steering, uneven tyre wear and a split rubber boot. Excessive play in a ball joint is an MOT failure. Catching these signs early usually means a simpler and cheaper repair. Electric cars are heavy and very quiet, so worn parts are often noticed sooner than on a petrol car.

Quality and Part Numbers
It is made by Febi, a long-established German parts brand, to match the original part in fit and function. That makes it a factory-quality replacement that fits without modification. The Febi part numbers are 198928 (left) and 198927 (right). It replaces MG part numbers 10782953 and 10782954. As a direct replacement, it uses the same mountings and connections as the original. Check the part number on your existing part matches before ordering.
Fitting Advice
Use a ball joint splitter rather than a hammer on the knuckle, tighten the new nut to the correct torque and have the wheel alignment checked after fitting. If the vehicle is equipped with driver assistance systems, a sensor calibration may be necessary. Check the control arm bushes while you are working on the suspension. A split boot lets dirt in and wears the joint out quickly. Using the correct replacement part keeps your car working as its maker intended. If you are not confident fitting it yourself, any good independent garage can fit it for you. Keeping on top of worn parts also helps your car sail through its next MOT.
