Twin turbo Posted July 24, 2018 Share Posted July 24, 2018 (edited) Hi i had my supra in for control because of clunking noise.mecanic went over all those bolts holding sub frames.followed tourqe setting from repair manual but all those rear bolts bolts on the front suspension that show 53nm was tighted at least 175nm from before.the bolts seem so big and 53 NM seems so little for holding the subframe,can this be the correct setting.repair manual is for the us model and i have a jdm car,also Numbers of bolts does not seem to add up because there is one more in the manual when counting.

Twin turbo Posted July 24, 2018 Author Share Posted July 24, 2018 (edited) Thats strange i got nothing like that on page ma 8 in my repair manual from 93,it is the usa version Edited July 24, 2018 by Twin turbo (see edit history) Quote Link to comment Share on other sites More sharing options...
Scooter Posted July 24, 2018 Share Posted July 24, 2018 looks like a hexagon flange bolt 11 to me from picture i added,do you think thats correct I think the two lines aren't an '11' as such, but are lines that are present on a range of bolt sizes, which you can then look up the correct torque. So the two lines or '11' mean it's a 6T class, then you can look up the torque for the specific thread size (I'm assuming the subframe ones are 10mm because that fits in with the torque you posted up) Does that make sense?

Yes i agree with you but saw this link on ma 8http://www.mkivsupra.net/vbb/content.php?71-Maintenance Edited July 24, 2018 by Twin turbo (see edit history) Quote Link to comment Share on other sites More sharing options...
Scooter Posted July 24, 2018 Share Posted July 24, 2018 Sorry I see now! That is a massive difference between your original post (US manual) and the post above......given they are exactly the same parts of a manual!? I would be inclined to go with the bolt markings, if it's just 'tight' and you annually check them then you should be good ie it's rigid to the chassis? Over torqueing could result in a shear/snap at some point? Quote Link to comment Share on other sites More sharing options...
Twin turbo Posted July 24, 2018 Author Share Posted July 24, 2018 (edited) those repair books are from 93 and 97,and all bolts does have the same Toyota partnumber thru all years and models. Bolts are massive 12mm thick. Edited July 26, 2018 by Twin turbo (see edit history) Quote Link to comment Share on other sites More sharing options...
