I am embarrassed to say after being optimistic on here about spacer leveling kits, I now have a minor potential issue....

 

When turning the wheels and driving slow, I often hear pops on front end. I believe i have closed in on the issue and believe its to do with the sway bar.

 

Everything is tight, and the level is new, I don't believe there is any damage yet.

 

 

I am asking for help on tightening and troubleshooting the sway bar and popping noise from it.

 

Any advice? this is driving me crazy

Hey, did you have any luck figuring this out? Just put a level on my truck this weekend and had a clunking. Everything is tight, got it aligned and the shop said they tightened up the sway bar end links and the rattling seemed to go away but now it’s back again. Don’t really want to have to take it off now but seems like it’s a common issue from some of the forums I found.

Check the top strut bolts. They’ll seem tight when the suspension is hanging but then at ride height they will have slop and be loose. Impact them down.

When you complete your final torque down of the nuts for the suspension, do it with the truck on the ground.  Torqueing to spec on an unloaded suspension is no bueno.

Replying to this thread because it’s the first thing that pops up on Google. I had the same issue and it ended up being the sway bar links. GM updated the sway bar links in 2022 with longer ones. 
 

if you have a 2019-2021 Silverado, you added a leveling kit and you’re hearing a clunk at slow speeds check your sway bar links. Have someone rock your truck side to side on the front and go underneath of it and give it a listen.

 

You will need part # GM85590925.

      OEM Trailer Hitch Receiver - Impact tightened by shop

      By SoCal Angler · Posted

      After my recent rear end bumper damage, body shop has made the repairs and included a new OEM receiver hitch.  I started thinking about how it was tightened...to specs or by hand or ??.  I called the body shop and asked and they said it was tightened by an impact gun.  I said I wanted it tightened to OEM specs.  They said no problem, bring it to shop today and they will torque to specs, which they say is 74 ft/lbs.   A couple of questions,,,,   1.  Should new bolts have been used?  If so, how many are there (bill shows one and four (I assume different areas of receiver).   2.,  Since they torqued with impact gun and now are going to probably loosen and then torque to spces, will that damage/stretch the bolts?   3.  If old bolts were reused (truck has 9000 miles), is that a problem?   4.  Any other things iI may have missed with regard to receiver replacement?   NOTE:  Attached are the receiver hitch specs from my digital OEM service manual.  It shows to horizontal mounting bolts and four vertically mounted bolts.  Other sections of manual reference eight vertical bolts.   Thanks!

      Defective Brake Pad Wear Sensor?

      By newdude · Posted

      Is this supposed to be in English?  "close to 100 fake, new brake pads sign on the dash board"     Pull the wheels off.  Check the brake pad thickness.  Check the sensors out.  You could have good pads and the sensors aren't in to the worn out position, but have an electrical fault with the sensor or the plug wiring to the sensor.

      Tomorrow I go in for my third joint replacement in jus a little over a year year!  I am not worried about the surgery but I am a little annoyed about going through the recovery process again!  I keep my frustrations to myself as I do appreciate that I am truly lucky.  Knee, hip, and shoulder replacements are routine, safe and improve mobility.  The next couple of days will be slow but every day following will see steady improvement in my mobility.

      OCI, not when but why?

      Practical Application ISO 4406   I think this oil cleanliness thing is going to boil down to ones personal resolve. The information is there but applying it I believe will test your commitment to the machine. Implementation would involve building or buying a prefilter or purchase of an "ISOCLEAN" oil. Then installing a single digit micron bypass system. A good deal of testing and about 99.9% of you are saying at that point....yea.....not my cuppa tea. So what can you do?    You already did the first step. Get educated and leave the bias at the door. Be aware of the its, cleanliness, importance.    Do your own work if you can. Keep the equipment clean. Not just your funnel but the engine bay. Use sealed containers. Think it through.    I believe you will find, as I did, that the tightest absolute full flow filters (Beta 200) will be around 20 micron. That will yield on average a Beta 75 of 10-15 micron. They are few in number by brand and price point. Loose filters are a dime a dozen and even the best brands have lines of loose filters. Some cleverly marketed as "Extended Service". Others will market flow over efficiency. But I think the take away once informed is that the extra cost of the best offered is a bargain. There are cheaper filters with good efficiency that are equal in performance to niche brands with big prices. Your Quick Lube is about a 40 micron unit. This is where your dealer is a plus. the AC-Delco filter is a good step up from those places. Even better if you specify the UPF line.    Be skeptical of marketing. Buying an oil that is made from GTL advertised as the cleanest base oil is using a truth to support a lie. While GTL's are made from debris free gas the processing equipment and post handling is just like any other oil. It also ignores the fact that PAO's and Esters are also gas in origin. Any private prescreening testing you would do, and some have done, would yield a result only good for the batch you tested. AMSOIL and Schaeffer's have built a reputation for paying attention to this detail.    Context. Cold starts account for at least 75%, or more, of an engines wear. But of the remaining 25% ish, over 80% is caused by particle count. Now where do we find high milage motors that use this type of information efficiently? OTR trucking!      Now, anyone want to build a prefilter or off line cleaning system anyway?
