Thanks, just one remark: you should tighten the bolts when the car is on it's wheels again, not when the wheel is hanging down. Tightening the bolts before that will stess the bearings.
Hi @pgapieper, you are correct on this, suspension bush mounting bolts should be finally tightened and torqued at the natural resting angle. This can be achieved by lowering the vehicle to the floor with the wheels on, or can be simulated to achieve the same result. We noticed we mentioned this in our other Tesla suspension video, but it missed the final edit on this one - apologies.
Great video thanks, very clear. Tesla discuss bolting up the new arm at the old set ride height. Is that just for air suspension, should we jack the hub up a bit before torqueing up anyway? They also instruct a 4-wheel alignment check afterwards.
Hi @Toob41, Delphi always recommends to torque the bush bolts when the vehicles weight is resting on the suspension, and with the vehicles ride height set to standard. This is where the vehicle will spend most of it’s time, and it would put the least amount of twisting torque on the bush. However Tesla also provides an additional step, which uses a ‘ride height tool’ which sets the arm angle at a specific height, with the aim of allowing the bush to sit at its natural position. Where this tool is not available, placing the vehicle on the floor with the vehicle in standard height, would achieve a similar outcome. After any replacement such as this it is indeed best practice to check and adjust the wheel alignment for toe, caster, and camber. Many thanks, Delphi Technical Team.

Hi @benc1927 thanks for the question. We try to find a balance between detail and ensuring we show the most interesting content. The torque specs were checked using Delphi VTI (technical data) and applied once the weight was on the vehicle.

You did not show how to remove the first top bolt! WHY?
Thank you for pointing out frunk multiple times. I wasn’t aware of it
Thank you, what is the sku number for that upper arm?
Hi @johnthomas77704, looking from the back of the car L/H = TC8273 and R/H = TC8272. Hope it helps😊
Have actually done this work this weekend on the back of this video. Thank you. Cutting that bolt if bit of *itch took 4 blades.
But now sorted.
@AdrianMcDaid , great job getting the work done! 💪
Excellemt job Phil. Nice and precise and thanks for mentioning the air suspension verstion
Missing a crucial piece of information: the torque specs?
Another great Video. Found the other videl you guys did on lower control arm, needing cut the bolt very handy.

@@DelphiTechnologies perfect. Thanks 👍
Good job Phil!
Great Video. Thanks
Great video and looks super easy.
Awesome video, I'm about to do both of mine due to them squeaking 😂
Thank You 🎉
with control arms torqued in this position, you are drastically reducing the lifetime of the bushings :)

No torque specs?
