just read like 20 pages of this thread. Looking to lower(level) the back of my CCLB. I am looking to go with shackles but after reading the issues with pinion angle, drive shaft length, vibrations I am wondering if these issues are only being seen with the shorter wheel base trucks? Has anyone dropped the back of their Crew Cab Long Bed (6.5') with 2" shackles and experienced any issues with the things mentioned above?

 

Thanks

Jim

Finished mine today. 2" shackles and removed the block. I had a humming sound when accelerating onto the highway so I added 2* shims. I noticed I have that hum now at full throttle from 80-90 (toll road speed limit is 80), no other time and no vibrations. Cruising normally anywhere else or accelerating at any other speed and everything is fine. Anyone have any ideas?

Your rear axle looks off center...What's up with that?

Not sure, I did look at other trucks in this thread and a few others looks the same.

Guess it's a little late for the warranty issue. 200 miles and just but some black bow ties and a belltech 3/5 kit on it. Never had an issue at the dealer with the 2007 I had. Did the same with it.

My 2015 LTZ 2wd Crew with 6.2 8 speed.

I've gone through this whole thread and I'm pretty sure I didn't see anything on using shock extenders. Pretty much using something to make the shock sit lower so it still has the same amount of travel when the back end is lowered a couple inches (either by using the drop shackles and messing with the block). I'm just trying to find a way to keep the life on my shocks and not loose life on them by making the back end sit even with the front.

It would look something like this:

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.

I cant help on this sorry, I only haul a Mx bike that's 200 pounds once in a while, but haven't noticed anything.

I don't like the additional rubber bushings. Prove me wrong, but the additional rubber bushings would introduce more lateral axle movement.

So if I measured everything correctly, Im having to replace my 2* shims with 4* shims. Gonna do it wednesday. When I look at my truck the rear sits lower than the front with the 2" shackle and block removed. If I still have any vibration issues after the swap Im taking it to a driveline shop and letting them measure everything out.

 

Now im really considering getting spindles for the front. Im really digging the lower front. My only concern isI dont know the torque specs for the upper and lower control arms and tierod ends. Does anyone have that info?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
