Re: 2WD C10 Modern/Performance Alignments
Bump for alignment stuff.......
Had my Chevy in twice so far to get the front end alignment, and it just wasn't good enough. Same shop just did my Tundra 3 times and still couldn't get that right. They used to be good........ Anyways, I got kinda peeved at the "that's as good as we can do" line, so I went and bought a QuickTrick alignment kit. Expensive bugger for what it is, but it works pretty decent. Spent the last weekend working on the front end trying to get it where I want it. Truck is lowered 2"/2" with just springs, all new front end wear parts, otherwise stock. First time I have ever attempted any kind of alignment myself------but I am a mechanical engineer, and I have taught people for years how to laser align pumps and compressors. Took a bunch of trial and error and head scratching, but I finally got everything going the right way and managed to not destroy anything. By the time I was done, I had to remove half of the rear self aligning washer on the right side, and had a single 1/16" shim on the front of the left side. Nothing else. Now I have: L Camber -.7 degrees R Camber -.7 degrees L Caster 1.8 degrees R Caster 2.4 degrees Total Toe 3/16" in. Only downside to the Quicktrick is you can only do total toe, getting the wheel set straight is trial and error. Today I got the chance to get the truck out and drive it to work and back. Ran it up to 90 mph, drove some side streets, took a few hard corners. Feels pretty good. Nice and stable, doesn't wander or pull at all. Steering is pretty "normal", not dead and not twitchy. Seems pretty good. Return to center still as lazy as it has always been, but I'm used to that. I know now I can get a little more caster on the left if I want to, but the right is maxed out without doing the lower control arm mod. I'm on the fence at this point whether that is worth the effort or not. Not real sure how to quantify any improvement I would get. Next I need to try to fix the alignment on my lifted Tundra. That should be a riot.

Re: 2WD C10 Modern/Performance Alignments
I had it 1/8" out and it felt weird.

Re: 2WD C10 Modern/Performance Alignments
Really good job! That stinks that the equipment will only do total toe. As far as the Caster Mod is concerned I feel its totally worth it and no I haven't done it to mine yet but I am confident that with 5° or more return to center will greatly improve and higher speed stability will be even greater.

I'm still debating between doing the LCA castor mod and just saying screw it and buying the tubular control arms. Probably do all of it at once when I do the disc brakes, which won't be for a at least a year or so.

Re: 2WD C10 Modern/Performance Alignments
You can get a shim kit for under $10 from Harbor Freight if you have one nearby. I use that kit and it works great. If you don't have one close you can order it online.

Re: 2WD C10 Modern/Performance Alignments
Yup. Thats the one. On a side note, I got an 09 Silverado not too long ago. I'll be looking into doing some alignment improvements soon. Both before and after a 4/7 drop.

Re: 2WD C10 Modern/Performance Alignments
You guys are using a Hunter machine. See if this link helps dial it in a little better.

Re: 2WD C10 Modern/Performance Alignments
I live in the U.K so getting stuff done on my Truck is just that bit harder, the shop I go to will do my Toe, because as luck would have it it's on their computer, but they will not touch the Caster/Camber. So I just had my Toe done today as the truck was pulling to the right, I've had to mess with the camber/caster at home on the drive but still don't really get it, anyway drove out of the shop and its still pulling to the right.
Frustrated at my lack of understanding of technical stuff, im going to have to post this and ask, whats it telling me?

Re: 2WD C10 Modern/Performance Alignments
First thing's first....swap the front tires side-to-side. If steering is neutral or pulls left you have a tire issue. Hopefully it'll steer straight. Critiquing the other angles if I may, your caster is too shallow and should be between 2 and 3 degrees from the factory. If you can dial in more than 3 that'd be great Too shallow will cause wander other issues that will affect the stability feel of a vehicle.. I'd like to see your camber under 1 degree negative. I understand you frustration. If you'd like, post pics of your shim packs and I'll see if I can help get you straight.

Re: 2WD C10 Modern/Performance Alignments
Nick, I took the wheels off and switched them round as you suggested and to my complete surprise the truck now pulls to the left...how is that possible? is there a right and left wheel because its as different as putting my shoes on the wrong feet
Does it need to be aligned again? surely not!

Re: 2WD C10 Modern/Performance Alignments
Your truck has a condition know as Tire Pull. The old alignment is now "burned" into the tread causing the condition. Swapping tires side to side proved this. The truck now wants to go left. If your tires are the same all the way around you do have the option of swapping one of the tires to the diagonal corners to see if the pull goes away (left front to right rear or vice versa). The only other option if you were serious about eliminating the pull is to purchase a new pair for the front. Aligning it again would not show any improvements. If you decide to mess with the shim packs to correct caster and camber you'll want to have the alignment rechecked.

Re: 2WD C10 Modern/Performance Alignments
Thank you mate, I really do appreciate your help and advice, I will swap the wheels and let you know what happens, and I really want to get a handle on this whole caster/camber thing, so i'll take some pics of the shim packs tomorrow.
Thanks

Re: 2WD C10 Modern/Performance Alignments
Well Nick here's the scooby, switched all the wheels diagonally as suggested, and when I took her out she drove nice and straight...Thank you man. I can't tell ya how over the moon I'am to have this finally sorted....BUT! when I took the front wheels off (one of which had been causing it to pull to the Right, then when switched it pulled to the Left) well I know why, one of the tires had a large bulge running about half way round the tire.
I took some pics of the shim packs for you also. First two are of the PS, the last iS DS.

Re: 2WD C10 Modern/Performance Alignments
That will certainly do it. I think you may also be missing some big rounded type spacers behind those control arm bolts.
