Senton Toe adjustment/fix needed

[zombiesai]

The truck took a significant hit on one side at the last outing and the left side front is significantly toe-out rather than straight or toe-in like it’s mate on the right. I’m not seeing any breakage or major slop in the steering rods to account for this. And the mounting pin appears to be straight. How do I get it back in line?
Suggestions and berating welcome.

Arm looks a little warped to me, but I don’t think that alone would make such a drastic change to the toe on that one side

take off your left wheel , think you'll find the problem !

 

[jkflow]

You didn't look hard enough. Take that side apart and look again. Something is broken.

Look at the front end picture of the left wheel , the hub is straight and the wheel is turned . x2 , something is broken .

Hello and welcome to todays edition of ‘What The Heck Did I Break?!’. The game show with wonder! Excitement! Massive Prize Packages (are not available)! See it all here!

Anyway, I’ve taken off everything that I think could impact the toe, plus a little more. I’m sure I could just upgrade to adjustable arms, but this is a great opportunity to learn.
What do you all think?

P.S. My calipers are out of juice. No measurements until later today. The metal blocks you see are for cnc calibration. They are straight and square to a tolerance we can accept here.


Edit: added some tire pictures. They’re the stock tire and rim combo no apparent damage or warping.

Your chassis looks odd, might be the camera angle but seems that the nose isn't straight out. I can't find anything wrong in your parts based on pictures above.

Are you talking about the center steering link ARA340179, or one of the connected link arms AR330446?

The center link (ARA340179) does have a little bent to it. Is it supposed to?

No, I'm looking at the front section of your frame. These looks bent like heck, unless it's a weird camera angle.
Are the arms and all mounting points square to the chassis?

You’re right, it does look like the front diff area plus the shock tower is bent/warped.

I would do a full front end tear down.

I meant the a-arm looks bent for the left side.

Take off the skid on the front and look under. I agree looks like the chassis under the front diff might have a break.
…although looking at your previous underside shots, it sure looks aligned. Might just be the bumper that’s bent up and making it look worse than it is.

 

[zombiesai]

I should have mentioned that the bumper is definitely broken. It’s been repaired a few times. I’ve been trying to talk my sister into printing me some replacements I’ve designed.

This is about as undressed as I can get it.

P.S. Who’s taking bets on this? I predict that if I put it all back together correctly it’ll be fixed.

 

[jkflow]

That's the idea
I'd take those pins out holding the arms in, I bet one is bent. Do the same on the outer side where the wheels attach. Only needed on the side that had this huge misalignment.
So far all looks good on the visible parts.

 

[zombiesai]

Unless someone has a new shiny idea, it looks like there isn’t a busted piece. Those pins are pretty straight.

I’ll put it back together this afternoon and get adjustable links if it isn’t straight.

 

[zombiesai]

Ok friends. I give up for today. It’s back together and still toe out on one side. As as added bonus: I’m only missing one screw!

Thanks all for the guided suspension and steering lesson. More parts soon!

 

[Rocketzx1]

Sure hope you cleaned it up a bit before you reassembled it

The left a-arm does look warped a bit compared to the right side.

 

[quiznatodd bidness]

Get some adjustable links off a granite/senton/vorteks. Then you can counteract that toe.

check the drive shafts if they are in properly.i had a problem sort of like this and it was the drive shafts that were out of place.which pushed the wheel out. and on my senton i can turn somthing with pliers and it will fix the tire offset

Remove both A-arms, lay one on top of the other and compare, or place an identical ‘non-used’ A-arm onto both and compare. Good luck.

Hinge pin/arm /C-hub is bricked.... perhaps even the Chassis is tweaked along with them? Look them over close. You had some major carnage there.
Surprised if your servo and servo saver is still functional.
