ok i have a 2007 gmc sierra 1500 with the stock 20's on it, well i decided to put my other 20" wheels and tires on that i had on my old truck. I got them on and went for a drive to make sure they are ok and the truck drives perfect, no vibration or shaking or nothing, BUT when i apply the brakes there is a terrible shake/vibration all the way up through the brake pedal....so what does this mean??

maybe not torqued correctly, or those 20"s may weigh more than the ones you took off??? Someone here will be able to help

When changing the wheels you didn't knock an ABS sensor did you? As the vibration up through the brake pedal sounds like ABS kicking in. Does the truck pull to one direction when you brake now?

 

If you put your old wheels on, does the vibration go away?

i don't know.....it doesn't make sense, yes they are torqued correctly.....these wheels are heavier but i cant see why that would matter....and it doesn't feel like the ABS kicking in...

there are clips you have to take off..

 

the stock wheels are cut out for the clips i believe and if you don't take the clips off for after market wheels it will shake...

There are clips on the rear drums that keep the drums in place during manufacturing. OEM wheels have a recess designed specifically to avoid these clips, after market wheels do not. Unless these clips are removed, you will experience shaking while braking. Run outside and remove your rear wheels, remove the retaining clips with a screwdriver and some needle nose pliers (you can trash them) and you'll be golden. Once that's complete, find a new wheel and tire shop because the guys you are dealing with apparently have no idea what they are doing. This is nothing new whatsoever. Good luck!

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
