Complete List of Suspension Torque Specs For the 5th Gen 4Runner

Do you use “good and tight” as a torque spec? It’s a common practice, but should be avoided. Here’s why!

We use torque specs to tighten bolts to ensure the proper clamping between parts.  Too loose and you run the risk of the bolt backing out and major malfunctions can occur while driving. Cranking down on a bolt can cause over-tightening which could lead to breakage or bending of the bolt head.  Incorrect clamping pressure is avoided by using the correct torque specs.

Torque Wrenches:

If you don’t have a torque wrench, invest in one!

If you can’t decide on which torque wrench to buy, the 1/2″ drive is going to cover most, if not all of our bolts/nuts. I would start with a 1/2″ drive if you have to choose one and then the 3/8″ drive as a secondary. The 1/4″ drive is nice for tight spaces but is not really needed for the work we do on our suspension. The 1/2″ and 3/8″ should cover everything.

Why Torque Specs are Important?

5th Gen 4Runner Torque Specs

I had just finished building my new 4Runner after a devasting accident with a deer that totaled my previous 4Runner on an Overlanding trip to Canada. And the last task was installing my new RCI lower link skids.

This requires taking out the rear lower link bolt, fitting the skid, threading the bolt back through the skid/link and then tightening the nut on the bolt.

That weekend, I took my newly built truck on her maiden voyage to Ouray, CO. Blackbear Pass, Engineer and Ophir topped my list of epic passes I was able to explore. On my way home to Denver, my truck kept doing a weird side pull, almost like a massive gust of wind was pushing the truck to the side which isn’t uncommon while driving on I-70 and through the mountains. I stopped and briefly checked it out but didn’t find anything weird.

The next day, my upgraded rear springs arrived (Dobinsons 749’s) so my fiancé started jacking up my truck to begin the swapping process.

He bent down to see if the rear tires were off the ground yet and his jaw dropped… “Oh, my, gosh” he muttered. I dropped down to see what he was looking at, and both lower link bolts had backed out and were being held on by threads. That, my friends, would have been a 2nd totaled 4Runner had they backed all the way out while driving 70mph through tight mountain passes.

These bolts were never torqued, and this is proof that “good and tight” shouldn’t be used or trusted.

Use this torque spec sheet as reference points when you are working on your truck. Do yourself a favor and print it out now for when you start working on your truck later. You won’t regret it.

On Toyota’s website for maintenance some of the intervals listed for while towing or driving on dirt roads to “torque nuts and bolts on chassis and body.” Which of these specs take care of this? Thanks.

Awesomeness! THANK YOU. Coming from the big diesel/RV world we had torque specs down. Now after that chapter is over and with all the up-fitting I want to do on my TRD ORP, this article was perfect timing.

I’ve been in the same scenario with one of my lower link bolts backing out. If that sight doesn’t make your stomach drop, I am not sure what will. I would also suggest that with each of these torqued bolts, especially with suspension components, that a “witness mark” be added to make sure that they aren’t moving once torqued. They make it simple to do a once around when you’re done for the day and in camp.
