bdcvg Posted October 30, 2022 Share Posted October 30, 2022 There are rumours that the torque specs in the TSM are incorrect for the 17mm head size bolts crossmember to chassis. TSM says 103ish ft lbs. Anybody know what is correct? Link to comment Share on other sites More sharing options...
silverton Posted October 30, 2022 Share Posted October 30, 2022 Everything I can find says torque spec on those bolts is 140nm, or 103ftlbs. 2007 wrx, sti, and 2021 sti all show 140nm. The 14mm bolts are 70nm, or 51.6ftlbs. Link to comment Share on other sites More sharing options...
bdcvg Posted October 31, 2022 Author Share Posted October 31, 2022 That's what I came up with too but reading reviews on the mount a few people have broken the bolts using 103 lbs. Link to comment Share on other sites More sharing options...
bdcvg Posted November 10, 2022 Author Share Posted November 10, 2022 Trans mount in no issues. 103 lbs worked fine . Side note the other noise I experienced after Group N motor mounts was 95 % erased by correcting tire pressures. The sweet spot for My set-up appears to be 35 frt and 32 rear.

Max Capacity Posted November 18, 2022 Share Posted November 18, 2022 Wow, 103ftlbs...I have never torqued those bolts, I just tighten them. I'm sure nowhere near 103ftlbs...for some reason, that sounds like a lot to me. But I do torque all lug nuts to 80ftlbs, using anti-seize compound. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

bdcvg Posted November 22, 2022 Author Share Posted November 22, 2022 Yeah I was surprized too but everything I could find in TSM or online had 103 ft lbs Link to comment Share on other sites More sharing options...

At least on all the current stuff, I remember looking up spec for my 2001 impreza and legacy and it is 88nm or, 65ft-lb... that seems WAY too light. But the wheels weighed less too.

BoozeRS05 Posted November 23, 2022 Share Posted November 23, 2022 Any opinion. Will I want to replace the original crossmember bushings with 198k miles while I’m in there? I also tighten my wheel lugs to 88ftlb fwiw 1 EB's Subaru journal - 2005 LegacyGT Wagon & 2014 Forester FB25 (2008 specB - RIP) IG@legacygtliving Link to comment Share on other sites More sharing options...
