Recently put 18" Fuel Pump wheels with BFG T/A KO2 tires on to replace the stock 20" chrome monsters. Bought from CarID and the wheel/tires were RoadForce balanced. That said, steering seems to have a bit more vibration in it at highway speeds. Couple questions. Does the truck come stock with a steering stabilizer (will crawl under and look this weekend)? Second, any recommendations on an upgraded stabilizer that will fit.

No steering stabilizer on 2011-2018 HD trucks. If you have a shake or vibration on normal roads around town I'd be having the shop re-check all 4 wheels/tires. Steering stabilizer will not fix your issue.

 

Do you have the front end turned up at all? If so how far (how many turns of the bolts)?

 

See below for why there is no stabilizer:

 

 

 

 

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

 

Condition/Concern

 

Steering wheel vibration or customers looking to add steering stabilizer for the Chevrolet Silverado and GMC Sierra HD 2500/3500 models.

 

 

Note: On 2011 trucks with a vibrations felt in the steering wheel, follow published SI diagnostics. The latest version of PI0650 may be helpful in diagnosing this condition. Recommendation/Instructions

 

 

The 2500/3500 HD trucks are not built with a steering stabilizer.

 

A steering stabilizer is listed in the parts catalog group 6.865 (steering linkage shock absorber) and is available, but is not intended to address vibrations or brake pulsations.

 

This part can be added, but is not intended to be used for a warranty repair.

 

Additional information: The 2500/3500 HD's are specifically built without a Steering Dampener Shock.

 

The explanation below can be used to give a more detailed description of how the 2500/3500 HD steering system functions, with respect to road input.

 

Steering damper's predominate influence is on large heavy impacts encountered during more extreme off road events. For smaller chatter/bump surfaces, the steering damper does not see high enough rod velocity to generate resistance force. For these situations, there is more mounting bushing compression than anything else.

 

The 2011-14 model year 2500/3500 HD steering gear system features the same knuckle steering arm to pitman arm length ratio as the previous (2010 and older) HD model, but the steering gear piston diameter is larger and capable of higher pressure, which creates more viscous damping in the 2011-14 model year 2500/3500 HD steering gear than the previous (2010 and older) HD model steering gears.

 

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

I agree it won't help shake or shimmy...but the difference on the road with and without are very noticeable and offroad is astounding.

 

Been there, done that...don't drink that koolaid.

Sure is some tasty Koolaid! My 04 and 06 (which both had stabilizers from the factory and both had similar miles as my 15 approx. 30-40k) handled worse offroad than my 2015 HD did. Steering was night and day better IMO.

In my 2012, on a (really) rough dirt road (good road, lots of rocks sticking up), mine would rip the steering wheel out of your hands...that's why I installed one.

Road force balanced or not, mud terrain type tires rarely balance out as well as "normal" tires. At highway speeds almost every set of after market wheel/mud tire set up I've ever run had some sort of vibration. Some more noticeable than others. Some I started noticing at 65mph, some started vibrating a little at 80mph.

Out of curiosity, what size tires?

Just my two cents.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.
