Will somebody let me know what the torque specs are for the rear shackles on a 2014 Siverado LTZ?

 

When I searched for 'torque', I found posts that said "torqued to spec", but nobody has posted what the spec actually is.

Bumping my own post.

 

Also need the specs for the U-bolts.

Also need the specs for the U-bolts.

Went to my dealer yesterday and a very nice mechanic looked up the specs for me.

 

Rear Spring Shackle Nuts: First Pass = 85 lb ft. Final Pass = additional 90 degrees.

Rear Spring Anchor Plate Nuts: First Pass = 59 lb ft. Final Pass = additional 130 degrees.

Lowered my truck with two inch rear lowering shackles,installation straight forward,no problems with ride or drive pinion . I'm glad I did this modification .

I've removed the blocks in the last 3 GM trucks I've owned using stock U bolts and nuts with "zero" problems. It levels the truck nicely. I just had to lower my headlights a tad.

Couldn't get the bed seams laid over far enough to get top bolt out. Ran out of time............

Try again another day

 

It took me a while also. I also loosened the bed bolts also to give it some give when I was knocking the bolt out. After I removed the bolt I cut off the bolt lip on the head so it would be easier to knock it back in.

Would it be possible to get a direct side view of your truck,by the the look of the pic. the stance of your truck looks perfect but I would like to see a direct side view if you have one ,just to verify the picture is just with the factory blocks removed correct?thanks

I put a set of 2" lowering shackles on the back of my 2014 denali, drives great until I hooked my trailer to it (approx. 2000lbs)

Got a bad vibration that gradually gets worse up to about 110 kph.

I'm thinking it needs shimmed but I just wanted to see if anyone else has run into this.

What did you do to get the 6" in the rear?

 

Its a rough country lowering kit. It says 5.5 inch in the rear and for whatever reason it ended up being 6 after it settled. Its a simple flip kit in the rear

I like those rims! What brand/model!!

 

Nice looking truck! :)

Has anyone who's played around with u-bolts ever seen them loosen up after a few hundred miles or is this more urban legend than sound engineering?

 

 

Yes, more then once.

 

I can name 3 trucks that I or my friends lifted and had the u-bolt loosen up after a few hundred miles.

I always recheck them.

    • 2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!  
    • Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?. 
    • He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it. 
    • I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!
