Drax240z Posted March 13, 2001 Share Posted March 13, 2001 Hey all. I was finally getting around to putting my front suspension onto my car today after the paint job. Anyway, I was going over everything with my torque wrench, making sure everything was to spec. I got to the 2 bolts that hold on each ball joint to the control arm, and read my haynes. 45 lb-ft. Hmm, seemed like a lot to me for those little bolts. (somewhere between 1/4" and 5/16" in metric) Sure enough, before I got to 45 ft-lbs I snapped the head off the bolt. Argh! The torque wrench is brand new, this was actually the first time I have used it. I am 99.9% sure it was set correctly. I think that either I was reading the wrong torque spec in my manual, or that it was incorrect. So can someone check their manual for me and see what the torque on those 2 bolts should be? (I only have haynes, so if someone has a chiltons or factory...?) Thanks in advance... ------------------ Richard Lewis Quote Link to comment Share on other sites More sharing options...
TimZ Posted March 13, 2001 Share Posted March 13, 2001 The FSM for my 78 shows 40 to 54 lb-ft for the castle nut, and 14 to 18 lb-ft for the nuts that hold the ball joint to the transverse link, which is what I think you are looking for. Looks like Haynes might have had their nuts mixed up. Quote Link to comment Share on other sites More sharing options...
TimZ Posted March 13, 2001 Share Posted March 13, 2001 ...you know... IdealZ sells FSMs on CDROM for ~$50. Don't remember what year Z you have but they have several model years covered. Well worth the investment. Quote Link to comment Share on other sites More sharing options...
Guest scca Posted March 13, 2001 Share Posted March 13, 2001 Drax..... being "anal" has its bad points.. i torque only heads, internal engine parts and flywheel (clutch) all other parts are done by hand .. ESPecially all bolts that are 10mm or 12mm nut size. Mike Quote Link to comment Share on other sites More sharing options...
Drax240z Posted March 13, 2001 Author Share Posted March 13, 2001 Yeah 14-18 sounds a whole lot more reasonable to me. I checked my other book (the wick humble one) and it gave the 40-54ft-lb listing for the castle nut. I'm not 100% sure, but I think haynes is messed up there. As far as the FSM goes... I have the engine from an 82, the chassis from a 72, which is insured as a 72, but has the same date of production as my last 73, a rear from a 79, a tranny from a 77, swaybars from an 81, alternator from a 81... well you get the idea. I may yet break down and get the 72 or 73 one. (not sure which) This bolt was a 13mm head size. Anyway, I am more than happy with the 14-18ft-lbs that tim quoted there, seems like a reasonable figure. I'm not anal about everything as far as torque goes, but I wanted to try my torque wrench out too! ------------------ Richard Lewis [This message has been edited by Drax240z (edited March 12, 2001).] Quote Link to comment Share on other sites More sharing options...
