Technical Wheel alignment knocked out by accident

[YellowPuntoFiat]

Hi,
somebody last week backed into my son's Punto while in the parking lot. Their bumper went straight into the driver side tire and now the wheels are no longer aligned. It does not look like a big job so I just wanted some feedback from the experts on the boards.

I attach a picture of the tie rod which looks to me like it was bent by the impact.

What else should I look into?

Thanks in advance,
Conrad
PS - I got a response from a different thread where I did see a discussion about wheel alignment: https://www.fiatforum.com/threads/fiat-500-sport-steering-wheel-alignment.514133/post-4840671 but wanted to also add it to the correct board.

Replace bent parts, as much as you can check/inspect them visually (or comparing R/L), then check the alignment/geometry.
But it must be good machine/system, that also tells the wheels spacing: L to R, and front to rear axle (2510 mm in Grande).
More parameters than average (mediocre) alignment shop does (angles only). Wishbone (track control arm) can move/shift (one hole is slotted).
Note that front camber IS "adjustable". Most "experts" will tell you that it's not (because service manual says so). Wrong.
Maybe brand new car was not adjustable, but older one (due to corrosion in the knuckle) will be. And will shift in case of accident.
Knuckle to shock absorber, two bolts (18 mm hex, bolt and nut). If there is a play, you have an "adjustment" (undo the nut, don't spin the bolt).

Looks like we will be doing the job in-house! So would like to get your help in assessing visually and suggesting what I should be removing and testing for. Below are some closer pictures which may help. But this is the assessment that I have made so far based on my own understanding.

1. Due to the bent tie rod end, It probably also affected the steering rack. So should I just get a second hand steering rack and replace the whole thing?
2. Lower arm looks like it should be replaced. I think it took part of the impact.
3. Since I'm replacing these other parts, does it make sense to also replace the sway bar? On one of the pictures it looks like it may be damaged but I will have a closer look. Not really possible to tell easily though because both sides are different.
4. What other parts should I consider replacing since I'm taking all this apart anyway?
5. Is there a way to check the driveshaft for damamge without removing it? Hopefullly, I can avoid having to replace that since I consider that to be much more labour and experitise (tools?) intensive.

Any other suggestions and things to look out for would be greatly appreciated. This is a 2014 Jet Black 2 edition which my son likes and that's why he decided not to just write it off...

So difficult to advise on this from my living room seat. However I've seen damage like this before and each part needs to be separately assessed. I'm tight fisted when it comes to spending money so will only replace parts that obviously need it. One I did had almost identical damage to the tie rod. couldn't see any obvious damage to anything else so I replaced just the tie rod and track rod end, adjusted the toe took it for a long drive - about an hour on various different roads and speeds - It drove nicely and subsequently showed no strange tyre wear the next time I saw it about a year later. I don't see any reason, from your pictures, as to why I'd do any different here. Steering racks are remarkably tough and, especially if the shock was mostly applied to it along the axis of the rack, no reason why it would need to be changed. Of course check it for smooth operation lock to lock and for play in the bushing on the N/S end and against the pinion and bush on the pinion end.

Whatever you decide, the only way to be really sure it's ok is to get it on a chassis bench, like a Hunter, and check all the angles. A check like this, if nothing needs done except maybe a wee "tweek" to toe settings, will probably be in the region of £80? Been quite a while since I've had one done.

Somewhere on the forum I've done a description, with illustrations, of my home made tool for checking toe - If I can find it I'll post a link.

I agree with the above. Check every part separately and change the bare minimum. Currently this means just the inner and outer tie rod.

Take more pictures and post them here if you aren't sure.

Ah ha! found it, enjoy:- https://www.fiatforum.com/threads/t...anything-else-people-commonly-call-it.502610/

Something similar occured to a friends 2003 golf. Needed inner tie rod, outer tie rod, lower suspension arm ,shock absorber and drive shaft . Followed by wheel alignment. Its done 80,000 miles since .

Of course this simple tool of mine only allows checking and adjusting of toe. Castor, Camber, King pin inclination etc are all aspects of steering geometry which should probably be checked following damage like this and you'll need to find someone with a "proper" alignment bench for that. It's not completely impossible to do at home but very difficult. However incorrect toe or the need to reset it after replacing steering/suspension components is a common job and that's what mine was designed to facilitate - Not to deal with crash damage.
