Hello all, My Sway bar was hitting my CV axle, as the title says. So I crawled under some trucks at the dealer to see what stock trucks are like and it turns out that the new TB/AT4's have longer end links then my 2020 TB. The new end link has a 3 inch rod vs the 1-3/4 inch OE part.

 

The part number for the longer end link is P/N:85590925

What was the price on those?

 

I noticed when I put my 5100’s on at TB height I had to loosen up the sway bar bolts and pull it down from where it rode stock.

Have a 2020 rst Bilstein 6112 at 2inch made 1/2 spacers where the sway bar  bolts to frame to lower bar so to not put to much stress on the links. No Rubbing.  Gm parts direct has them for under 20 dollars a link under that part number 85590925 you posted. But if I search 2020 TB vs No TB both come up with the same part number 84367821. The sight won't give sway bar link parts numbers for anything 2022 and up. What year truck did you crawl  under?

I got that part number from a 2023 custom TB. Those links are also on all the ZR2 and new AT4's as well. I was able to reuse the old nuts from my original links.

What size lift in in your truck for the sway bar link to hit the axle?

I put a 3inch lift in my 2021 no TB and my sway bar hits my cv axle also.

There should be some kind of spacer to drop the sway bar or longer sway bar end links to prevent that.

I have the front leveled 1" and it's a TB. So we should be around the same.

So you did install these end links on your 2020 with no issues? I am having the same problem with my 2021 RST z71 with RC3.5” and thinking about trying this for the solution but can’t find much confirming they are compatible.

Did you remove the sway bar at any point? I think you have it backwards if it's rubbing, even with a lift.

So thanks to the Facebooks, was pointed to this page. 20 rst at 50k, 5100 front set to level. Noticed a rubbing noise while turning right, and randomly other times, but predominantly right. Seems like this might be the fix so ordered the longer ends and fingers crossed.

OMG, I'm sorry for the late reply. Yes, they bolted into my factory swaybar and A-arms.

Hopefully it fixes it for you! I imaging you'd see marks on the cv axle like in the pics if this is the issue.

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
