    Stock caliper bolts are rough to remove. Especially since they are Allen heads. I had to cut through the hardened steel bolt to get it off. Just enough for a 3” cutoff wheel. Your videos are very helpful as I just purchased my first A body and starting my upgrades from stock.

    I have a 1968 Chevelle, and it had drum brakes on all 4 wheels. I do now have disks all the way around. I too now have the tubular A arms as I pulled the ball joint, while driving, out of the lower driver's side, and don't ever want that to happen again! Today going over a larger bump on Hwy101, the car took off to the right. Not a great feeling! I'm now going to order the new parts shown here. I have to ask if I'm going to have to take it back 8n for an alignment as I just had it done. I'm also going to check the tie rods as I haven't since I stuffed the wheel up into the fender. Thanks for the video!

    Usually bump steer fixes convert the outer tie rod to heim and you use a regular bolt and shims to correct.
    What I noticed was you have drop spindles. They make factory bump steer worse by moving the spindle location away from the steering arm. That gives the spindle more mechanical advantage over the steering arm.
    Another bump steer related issue our cars have is a positive camber gain. Which makes the top of the tire go out (instead of in) and lifts the inside of the tire off the ground. A sudden camber change over bumps will also cause the bump steer feeling. The best way to correct for that is a tall ball joint. There are some tall spindles available also. This will give negative camber gain, better cornering traction, and increase tire to fender clearance.

    • @FastMonty
      @FastMonty  2 роки тому

      Good stuff, brother. Yeah, drop spindles, and after market A Arms will make the stock bump steer issue worse. Which is why these are an ideal fix. Agreed about taller spindles, which is on my to do list, but not an easy project. (I really don't want to take off my perfectly aligned fenders. :) Anyway, camber can always be adjusted, as detailed in my alignment videos. Thanks again!

So, hopefully you'll see if the alignment changed, next week. Thanks!

    My understanding is bump steer is much more pronounced with rack and pinion steering??? I have a 67 Chevelle with stock steering/suspension and would love to upgrade my steering. I'm told there isn't much point in upgrading to rack and pinion steering unless you upgrade suspension to tubular A arms? In fact I hear that rack and pinion upgrade without suspension upgrade can cause handling issues?? Any advice/opinions?? Are there upgrades to the stock steering box/system that can reduce that mushy vague stock steering feel without going to rack and pinion and is rack and pinion worth it for a cruiser type application (ie not looking to make a track car just something that handles more like a modern car)??

    • @FastMonty
      @FastMonty  День тому

      Good questions! I don't know much about rack and pinions... besides they're a pain in the ass to install into an A Body. That said, yes, you can upgrade your current steering box. Mine is from AGR. 12 to 1 ratio. I love it. Have fun!

    The video on the GW site is pretty good at showing how these steering arms correct bump steer. They show moving the whole front up and down with before and after measurements. Would it matter if only one side goes up while the other side goes down as happens during hard cornering? Its amazing such a small change makes such a big difference.

    • @FastMonty
      @FastMonty  2 роки тому

      Yeah Ryan, that GW video is eye opening, for sure. Which is why I bought em. The bump steer is an independent issue, from side to side. So, there's no telling what our wheels are doing from left to right, my guess is one is toeing in, and the other would be toeing out. I think I'd much prefer we keep that change to a minimum, ha, ha... thanks for the comment!

I bought the drop cups with spacers, I drop like 2" my tahoe 2016 but a that Point the Outer Tie Rod is not horizontal like the chevy comes as factory o maybe a little down inclination, now after I drop it, has some up inclination , so when you get a bump in the road in only one side, the outer tie rod pull too much towards in the wheel in and it becomes inestable the car, I feel the car shake in the front a some inestability and my wheel steering shake too, so if you drop more the car is going to be worse, could you recommend me any solution, I thing that with the spindles is the same thing, what do you thing, thank you, good video.

      I was looking at the coilovers where the stock spring is replaced and the coil over is mounted at the shock locations. Global West states that the stabilizer bar in their kit distributes the force/stress from the shock mounting area. Im not sure how much of a benefit it would be. I guess the overall question is if your happy with GW.

    Hi Mike, great video, THANKS !!! My question is, what was your GTO doing as you drove it that made you replace the control arms. I have a 64 Malibu SS with tubular upper and lowers, disc brakes and a Unisteer rack and pinion system. After all this was installed I had the front end aligned. As I drove home my car was not pulling either way at all but it was drifting and I was constantly correcting and don’t even think of stomping on the gas. After watching your video and Global West’s as well I think bump steer is my issue.

    • @FastMonty
      @FastMonty  2 роки тому +1

      Good question... I think I mentioned it in the video, I hit a dip in the road, and the car darted to the left. If your car misbehaves when the suspension moves, you have a bump steer issue. It's also a relatively easy upgrade, as a "just in case" solution too... hope that helps!

    • @davidrosenthal735
      @davidrosenthal735 2 роки тому +1

      Hi Mike, after speaking to you last about my bump steer issue I determined it could be a negative camber issue I have and with the upper control arm cross shafts against the frame’s bracket there’s no adjustment in the positive direction. The upper and lower control arms are made by different manufacturers so I decided rather than using an offset shaft to replace the lower arms since I installed the uppers and have no idea of the manufacturer of the lowers, hopefully this will bring the bottom of the wheel inward. Another reason for this comment is I’ve watched several videos from others and so far have not seen a thorough explanation for this project. I see your GTO has tubular a-arms but no video of when you installed them. I’m very spoiled with the videos you produce as they are clear and complete. Thanks for what you do.

      Braking is incredible! Time away? I'm in the garage... not hanging out at a bar, not spending hours away on a golf course... I'm in the garage, at home. My wife appreciates that, more than you know. Thanks!
