Tesla upper control arm replacement cost: parts, labour, alignment

Updated 2026-11-06 · Version française

Front upper control arm, left, for the Tesla Model 3 and Model Y — Tesla OE 1188321-10-C (ZF Lemförder)

Short answer: the part is most of the bill. A front upper control arm for a Tesla Model 3 or Model Y is CA$89 aftermarket or CA$189 in genuine ZF Lemförder, per side. Tesla's flat-rate time is 0.54 to 0.90 hour per side, depending on the car, and its alignment tables call for an EPAS alignment check afterwards, not a four-wheel alignment.

Left and right are different parts: left 1044321-00-J (aftermarket) or 1188321-10-C (ZF), right 1044326-00-J or 1188326-10-C. Our aftermarket arm is listed for the Model 3 (2017–2023), Model 3 Highland and Model Y (2020–2024); the ZF arm fits those cars and the Model Y Juniper.

What a Tesla front upper control arm costs

How long Tesla's procedure takes

Tesla's North American service manuals give a flat-rate time for one front upper control arm, per side. The 2020–2024 Model Y has two versions of the procedure: one for cars with the structural battery pack and one for cars without it.

Tesla flat-rate time to replace one front upper control arm (North American service manuals, read November 2026)
Car	Tesla correction code	Flat-rate time
Model 3 (2017–2023)	31014002	0.72 h
Model 3 (2024+)	3101030012	0.54 h
Model Y (2020–2024), without the structural battery pack	31014002	0.66 h
Model Y (2020–2024), with the structural battery pack	31014022	0.90 h
Model Y (2025+)	3101030402	0.54 h

What the procedure involves

In Tesla's Model 3 procedures (2017–2023 and 2024+), the arm's mount is held to the body by bolts torqued to 35 Nm (13 mm socket) and 62 Nm (15 mm socket); on the 2025+ Model Y they are 34 Nm and 62 Nm. The 2017–2023 Model 3 procedure starts by looking at the tires for abnormal wear that might point to an alignment problem, and noting it.

Do you need an alignment after replacing an upper control arm?

Not a full one by default. Tesla's Alignment Requirement tables for the 2017–2023 and 2024+ Model 3 and the 2020–2024 and 2025+ Model Y all list an EPAS alignment check (EC) for the front upper control arm. Tesla's procedure says to add the alignment check or adjustment as a separate line.

If the car passes the EPAS check, no alignment is needed. If it fails, a four-wheel alignment check follows. In the 2025+ Model Y manual, the EPAS check is 0.1 hour, the four-wheel check 0.30 hour and an adjustment 0.9 hour.

The lower links follow different rules: one lateral link needs an EPAS check, both need a four-wheel check, and a compliance link needs none. Our lateral vs compliance link guide prices those links next to Tesla's times.

What the job adds up to

On a 2025+ Model Y (Juniper), one side is the ZF arm at CA$189, plus 0.54 hour of labour and the 0.1-hour EPAS check at your shop's rate. On the other cars, the arm is CA$89 aftermarket or CA$189 ZF per side, plus Tesla's time from the table above and the EPAS check.

Under warranty? Check first

If the car is still inside Tesla's Basic Vehicle Limited Warranty, 4 years or 80,000 km in Canada, have a noisy or worn arm looked at by Tesla before buying parts. Our warranty checklist explains what to report and when, and how Tesla treats creaks and rattles.
