not cheap, but a potential solution for your front control arms.

Well, I am getting to the end of my proverbial rope with this thing now.

Continue to be impressed by the killer stuff these guys have helped me out with on this car. Huge shout out to STS Machining's Scott and Taylor for helping with my idea.

I was having issues with the rear rubber bushings on the lower control arms. I hatched the idea of a delrin bushing for the rear that was captured in the cup, Taylor made the first set, a 2 piece design that would not be able to be pulled out the front of the cup.

Here is what the end result is. A 2 piece delrin bushing, the cup welded into the actual bucket that bolts to the car. For the first time I can without a doubt tell you that this is not moving around at all.

Getting machined



Parts cut and fresh out of the freezer ready to be installed.



This cup was cleaned and welded in place so that it cannot get pulled out.



Assembled







When I took these current bushings out, the one on the drivers side had come out of the cup so far that the flange on the backside was not even holding it in any longer. The passenger side had started to pull the cup out of the bucket.

No its not the Fancy Sellholm arms, maybe those can go in someday in the future.

SO now I have lower control arms that are not moving around, great should be problem solved right.....wrong.

Still does the same ****.

You can center the steering wheel, go out for a drive and it will move from left to right depending on what you are doing.

It seems to be getting worse. If I go hard on the gas, the steering wheel will be off center to one side, if I go around a hard turn, brake or something then it will be off center to the other side.

I checked all the front crossmember bolts and they were not crazy tight, drove it again this morning before work and same problem.

I installed new hardware on the steering rack when installed. Considering that it changes on hard launches, I am leaning towards something loose in the rear suspension.

Might have time to look at it over the weekend but have graduation activities from this afternoon through Sunday.

Any good opinions I am all ears.

Can you dab some paint on the rack and see if its walking around?

You have fresh paint on the boxes for the bushing. Are there witness marks suggesting its moving around in space?

I had similar issues with the v8 drift car, the rear end was moving around a bit under hard acceleration. The rear alignment might be playing into this as well.

When doing your alignments, are you taking it to a shop, or doing it with strings?
If a shop, which one?

I started putting paint pen marks on all hardware to ensure its not moving. The boxes for the bushings are not moving at all, the underside of those bolts are knurled and lock it in really well.

This is where I am heading now, is going over everything in the rearend to make sure that things are not moving around. Yesterday was the first time I saw it move and it was after a hard launch, that got me really thinking about rear links and hardware.

Done both. AR Auto did the first real alignment, other ones have been strings but its pointless really as stuff moves around upon the first drive.

Thanks for chiming in, its much appreciated.

Is it possible the engine is moving around enough under accel/decel to contact something or move something else around?

Thumbs up

If that doesnt work maybe try a stabilzer bar from the front like older ford style set ups. But thats a lot of work to redo that whole area.

It took me a day to figure out what you were talking about, then I recalled my dads 64 ranchero and I totally get what you are talking about. A forward facing stabilizer bar for the lower control arm. I hope I dont have to add anything like that, I already dont love the srut setup that I have...

Well, only had about 2 hours to work on the car this weekend with 2 Graduations to attend. One in Seattle on Friday, another in Portland for our Steamfitter apprenticeship program and then a bbq on Sunday for the Neighbor who graduated Friday night.

Got a little time to work on the coyote swap for my neighbor though, just about ready to set the motor in for the first time one night this week and I can finish up the motor mounts that I got started on.

I went through the entire frontend Saturday afternoon. I cleaned, torqued and put paint pen marks on every fastener. The only thing I found that even remotely budged was the 4 bolts on the Driver side steering arm. I got maybe 1/4 turn from 3 of the 4 bolts, but that was it. Not enough to cause anything to move.

I torqued all of the motor mount hardware as well as every nut and bolt on the crossmember, and all steering stuff. Nothing in the front is moving so its time to head to the rear.

I got the car up in the air, frustrated still..

I checked every nut and bolt on the rear axle, panhard bar, shocks, upper and lower links at the axle, nothing was moving. I reached up and put a wrench on the chassis end of the upper control arms and it wasnt more than hand tight.

I continued to find 4 loose bolts for the fronts. Uppers got torqued to the proper spec. I found the lowers loose as well. They had stover nuts on them but the stover nuts were not really tight.

I purchased new washers for the bolt, new stover nuts and installed with Blue locktite.

I took it out for a trip around the area to see what I had. For the first time ever the steering wheel was in the same spot the entire drive. I was hard on it too, accelerate hard from a dead stop, hard braking, steering left and right abruptly.

I paint marked all the hardware on the body for the rearend to see if it moves at all moving forward.

Never did I think that the rear suspension moving around could cause that bad of an effect on the steering. I am really curious to see what it feels like on track now. It feels so much tighter than it every has.

Live and learn right?

So, working out the little bugs now. I have a shake in the steering wheel at about 62 to 70 mph. I think its a front hub issue, but going to tear into it this week and start measuring things out with a dial indicator to measure runout.

Gave the old girl a bath yesterday and enjoyed it being mostly trouble free for a day



Looks pretty meaty sitting there.

Happy Monday and thanks for those who have provided help and feedback on this thing along the way, its much appreciated.

In the v8 drift car with a torn trailing arm bushing, I could change lanes while keeping the wheel completely straight if I romped on it. Rear steer is a thing.
Glad you got it sorted.

Its crazy to think how much it can change steering geometry by a small change in rear suspension. It kind of sucks to think that anything I do from here on our suspension wise is going to require an alignment. Going to get expensive fast.

Dropped the **** box off for another alignment today. Hope its the last one for a while.

Have to order up a couple of tires to replace the fronts soon. Think I am going to rotate front to rear here soon and see if I can flatten out one of the fronts and keep it for a while.

I need a tire sponsor.
