I just ordered Sidem parts for my 2013 MS off eBay, after reading this
thread that the Beck Arnley arms are actually
Sidem arms. The Sidem has the redesigned ball joint on the track (lower) control arms. $784 with taxes and shipping for 6 total parts (2 upper control arms, 2 lower control arms, 2 rear track control arms).
Rather than the weak link of a pressed-in ball joint in the track control arm of these Tesla cars, Sidem’s replacement track control arm is 1 part functioning with maximum strength. The ball joint cannot get detached when it is subject to high impact. As a result, a safe installation is guaranteed for the mechanic and the driver.
The Sidem, unlike the
Medvotech, does not include bolts. See below for the bolts, washers and nuts you will need from service center, assuming you are replacing all 3 arms (upper control arm, lower track arm and the rear track control arm) on both sides:
1004357 - bolt M10x1.5x100 [10.9] DP Znal-W (4)
2007059 - nut, M10x1.50mm (4)
1004350 - bolt Btnhd M10x1.50x57 [10.9] Znal-W (2)
1004351 - nut HF M10x1.50 [10] Znal-W (2)
2007108 - bolt H cam M14x2.00x114 [10.9]-G270 (2)
2007115 - washer cam M14x38x6x2.5[10]-G270 (2)
1006484 - nut CLN Hex M14X2.0 [10] Znal-W (4)
2007106 - bolt H cam M14X2.00X114 [10.9]-G720 (2)
2007107 - washer cam M14X32X3X2.5 [10]-G720 (2)
Finally parts cross reference. This is for the RWD MS 2013-2016, but confirm using epc.tesla.com for your MS.
