Ubolts under torqued

BTW, thanks again, 4WD.

This fixed my axle wrap, firmed the rear suspension back to where it was when it was new and also fixed the 60 mph drone problem. It should probably be in the owners manual to retorque every 30k.

 

I found several charts with similar values

 

Took mine to the shop for other reasons. But I had them to check the ubolts. When I went to pick up the truck the tech told me that mine were so loose that he thought his torque wrench was broken. He couldn't believe it. He torqued it to 73#. 2 month old truck.

 

Hey you're welcome bro', don't try to torque over 70-75 ft lbs, theres already some thread stretch going on by default, just make'm good & snug

Glad you had them check.... this is all I wanted members to do is check, & correct if neccessary..

I looked at the voting poll & gotta say, I'm not buying it , theres more than a few members that shouldn't have even voted because they've already had them off,changed springs or got their trucks after suspension change etc;

 

I agree, some people probably just voted without even checking.

 

Despite my initial skepticism I tightened mine up to 60 lbs today. I tend to be skeptical of internet ideas, but I think this was a good move. And yeah, it took a lot of turning to get a click. I'll probably end up at 80 lbs once my conservative self loosens up some more.

 

With all due respect, I'm not an internet idea .. I work with leaf springs/axles/Ubolts all the time & almost all exclusively Tacomas, 2nd gen Tacomas....

Sorry but I find your comment rather condescending

I started this thread based on MY experience & my concerns for other members who may or may not have this issue, but none the less I'm glad you threw caution to the wind & took a chance on the internet idea provided......

 

Has anyone heard anything from Toyota directly about this?

I understand what the general consensus and those with mechanical knowledge say, but hearing from Toyota in writing would certainly make me feel better before tightening another 40#

 

Well good luck with that, Chris4x4 addressed Toyota a couple times IIRC & never recieved any response....

& quite honestly a note from Toyota would not sway me one bit from torquing them to at least 70 ft. lbs

 

Makes sense I suppose. I will check mine this weekend, tighten if necessary, and report back.

Edit: Thanks for bringing this up OP

 

Sure thing & yes please let me know what you find...

 

I wasn't trying to be condescending, it's just that I tend to stick with the status quo. It takes a little while for a new idea to sink into my brain, that's just how it is. Thanks for the thread.

 

Probably one of the most knowledgeable guys you'll meet when it comes to rear ends . Honestly though.....there isn't another dude I would trust more about this stuff than Doug. He definitely knows his shit.

 

Stumbled upon this thread, so I decided to check mine...fortunately, my u-bolts still look like new after 7 years. No rust in NM...

They were slightly less than 40 ft/lb. I proceeded to torque them up to 70 in 10 ft/lb increments.

Thanks to OP for the thread...you never know what valuable information you are going to find on TW...

 

No problem my friend & I'm glad you checked....

 

My ubolts are as tight as I can get them.

 

Hey as long as there all about equally tight & not stripped yer good bro'....

 

Stupid question, the first and 2nd gen rear ends are similar.

What does the fsm state for a first gen?

I'm on my phone otherwise id look it up

 

90 ft.lbs IIRC

 

A very good friend of mine and vet knowledgable mechanic tellse "tights right and too tights broke. And a good cross thread beats a lock nut any day"
