MEYLE engineers solve Tesla’s squeaking problem

Hamburg engineers solve Tesla’s squeaking problem and develop technically enhanced control arm for Tesla 3 and Tesla Y

Electric cars represent relaxing, noiseless driving, which is exactly what buyers appreciate about them. They combine quiet with quality, innovation and maximum comfort. But then the Tesla’s steering suddenly begins to squeak, which is when the community surrounding the premium electric car sits up and takes notice. Around the world, more and more drivers of the Tesla Model 3 and Model Y are reporting irritating squeaking sounds. What’s going on? That’s exactly what the engineers wanted to find out at MEYLE (, the spare parts manufacturer based in Hamburg and one of the market leaders in the independent aftermarket. The MEYLE engineers analyzed the problem and developed the solution: an improved, technically enhanced control arm that reliably stops the Tesla from squeaking.

In September, the new and improved MEYLE HD control arm for the Tesla Model 3 and Model Y vehicles will be presented as a prototype to the general public for the first time at Automechanika, Europe’s largest automotive trade fair for parts and accessories. Because the defect could potentially affect up to 700,000 Tesla drivers around the globe, the spare part, which will be available from early 2023, will offer Tesla drivers and workshops an alternative to the original part which is technically refined and thus ensures Tesla’s typical driving fun. Another benefit: thanks to collaboration with ClimatePartner, the MEYLE part is climate-neutral.

Getting to the heart of the problem. And solving it.

‘Many everyday objects can begin to squeak after a certain period of time,’ says Stefan Bachmann, Head of Steering & Suspension at MEYLE. ‘But we weren’t expecting this to happen with the Tesla. We’re connected with car enthusiasts around the world and always have our finger on the pulse of the latest trends and acute issues. 

Particularly when it comes to sensitive suspension technology, we immediately set out in search of a potential solution. Because we’re driven by principle, we wanted to get to the bottom of this strange squeaking sound straightaway.’

The MEYLE principle. Our engineers take a closer look …

MEYLE’s development team identified the cause of the squeaking sound after numerous tests: the Tesla control arm had been designed with insufficient moisture protection. As a result, water penetrates the ball joint, which ultimately leads to the unwelcome, irritating squeaking sound and, in rare cases, can compromise steering precision.

To solve the problem, the MEYLE engineers produced a prototype with a new design and performed sound development work.

‘Being able to hold the first prototype in our hand after having identified a weakness, looked into the causes and performed development work and countless tests is a special moment for us every time. Especially for a premium car like a Tesla. After all, moments likes these are precisely why we do our best every day,’ says Stefan Bachmann, Head of the Steering and Suspension Product Team.

… and make it better

Unlike Tesla’s control arm, which is made from a combination of steel and plastic, MEYLE’s control arm is made from high-strength, forged aluminium, which reduces weight and increases stability. The ball joint itself has a larger diameter than the original part and can distribute forces across a bigger surface, which is essential for a durable spare part, considering the large and frequent loads the high-performance vehicles are exposed to. But more importantly, the design forgoes the use of crimping, which prevents water from penetrating the HD control arm and thus eliminates the source of the squeaking sound. As a result, the MEYLE solution lasts longer and keeps the driving fun going almost indefinitely.
