Can someone tell me the torque specs for the bolts holding the rear spring retainers and the bolts for the rear shock? I have a Haynes manual but the torque specs are limited and not clear, thanks

Welcome to this forum!

When fastening torque is not specified for a bolt in a specific location, we can default back to a "typical torque range" for a given fastener size...and a mechanic develops that as a function of experience from similar sized fasteners where torque is specified (and maybe a few that he has broken off "not knowing his own strength")...

...or you can refer to the other rule: "Keep tightening it until it suddenly gets loose, then back off a quarter turn..."

Happy Wrenching!

The Volvo green book does not provide torques for those bolts. The following provides a guide to torqueing SAE fasteners:

https://www.boltdepot.com/fastener-information/bolts/US-Recommended-Torque.aspx

Remember that these are the thread size, not the nut / bolt head size. You can tell the grade of the fastener from the markings on the head of the bolt. If you have a nut which will typically be unmarked assume that it is 5 or less. I am going to hesitate a guess that the torque recommendation chart is for clean unlubricated threads. I look to put everything back together with a liberal slathering of anti seize (especially suspension bolts) which acts as a lubricant so I tend to err with slightly less torque than recommended.

Thanks for link to chart!

I am also a religious user of graphite/nickel filled Anti-Seizes and was also wondering about the dry vs. lubed torque thing a while ago...

...so I contacted Loctite's customer service and asked them about it...application engineer Rich Lockery there sent me the "K-Factor Charts"...it basically shows to reduce the specified torque by 10-15% when using Anti-Seize, so I would say you already had it well under control...but just in case you're interested, see: https://www.sw-em.com/anti_seize.htm

Well torqued Cheers!

Interesting notes on the application of anti seize. I would not have thought about cable lubrication. I have never applied AS in cold weather so I don't know whether it becomes very viscous or has a very consistent viscosity versus temp characteristic. If it has a flatter characteristic it might be a good option for the throttle cables because I find most greases tend to make for stiff throttle operation at reduced temperatures. To avoid this I typically uses 'oil'; but, these tend to disappear quicker. AS might be the hot ticket!

Freezing it will increase viscosity more sure, but being grease based, it's already at a very "high viscosity", and I don't mind that characteristic (it means it stays put)...the other characteristic I like is that liquids or even greases can be displaced, but the particulates cannot)...that's why I prefer it for certain low movement/high bearing area jobs like cables and linkages, not to mention anti-corrosion jobs...after ACZP, it's my second favorite product to have on hand during service...

Cheers

Great, thanks for all the feedback. I bookmarked that chart, Im pretty good about guessing torque specs these days but always like to double check when possible

Thanks! and thanks for getting that alternator bracket over so quickly ( I think I bought that from you ), that's tomorrow project
