Re: Tyre wear update
Interesting Document Crashbang, thanks. Makes sense too, apart from the ambiguity of 'apply a force to the wishbone towards the interior of the car'. From the diagram the force is applied to the lever towards the centre of the car. The force to the wishbone is applied towards the outside of the car. Picking nits? Well probably, but ambiguity is the mother of nause-ups so I think it right to pick nits on matters of detail.
Well done FIAT for getting you fixed up. Mine was inspected recently and I was told the work had already been done. Once the front tyres start to wear unevenly they continue to do so after the fix has been implimented apparently. I have to believe them, so now I have a good pair of boots on the front again we'll see what happens.....

Re: Tyre wear update
That's a huge 6MB file
Here's the bulletin in 15 seconds
Loosen the two bolts shown
Use a lever on the wishbone here to take up any slack in the flexi bearing
Retighten the bolts to 10.5 daNm
Get your toe in rechecked afterwards
Why that took 2 pages to explain I don't know

Because if you read the thread I asked for help as I am not computer savvy and tried the best I could. I though it could be useful. How ungratefulThat's a huge 6MB file

Re: Tyre wear update
Hi Crashbang
You must have misread my post somehow
I said that 6MB is a huge file (which it is if you're downloading on dial up) and people needed Adobe and winzip to extract it and were struggling to view it so i reposted the document for you as you said you "weren't computer savvy"
In doing so, the instructions boiled down to no more than
Loosen these bolts
Lever wishbone to take up play
Retighten bolts
so I wondered why the original Fiat document took 2 pages to explain that
And so, sorry that you read my post in a very different way than it was written. You obviously took the time and trouble to scan and post the document, the same as i took the time and trouble to rescan and reformat it, for the benefit of everyone here which is always appreciated

Front tyres should be as near as dammit parallel. Fiat quote tow in 1.5 +/- 1mm on my CD but you need to watch your expensive tyres and decide for yourself. If you've lowered it then it needs checking again
They can do tracking until the heifers come home but if you have a worn track rod end then as soon as you start driving you have massive toe out, torque steering and "way hay" tramlining
So check for wear by moving wheels in horizontal and vertical plane when jacked up and check for wear at the track rod ends ( aka tie rod ends)
It's usually the driver's side that goes first. Mine was gone at 35k miles.
A lot of tyre shops still track them at 2mm toe out and that's wrong as that was a figure bandied about many years ago and everyone was complaining of front tyre wear. Luckily i never go to tyre shops for tracking
Check in the Stilo Guides for how I check my tracking by eye. That's what i do and all my tyres wear down really flat and even until they get to the limit. It's no good saying your tyres are tracked as per the book and next time you look your tyres are a wedge of cheese. Check them every week or pay the price- quite hefty too
Tyre pressures are also an issue if wear is on the outside and also causes bad camber following until you put them at the best pressure for your tyres and car but that's a different story. Do a search on tyre pressures and decide for yourself

Standard toe on the Stilo is toe-out surprisingly!
However, extreme end of allowed range is 0° Toe which is what mine is set at and I'd recommend you do the same.
P7 tyres seem a very good choice for the Stilo. Not sure if this is due to there asymmetric design or not but I can't detect any wear on mine yet
Other members have reported the same too.
As always a full 4 wheel alignment check is critical.

So you think it could be a toe out problem?
It looks like a camber problem but I've been told that that's not adjustable.

I phoned the hub in cardiff and they said you can't do 4 wheel alignment on a stilo as the back wheels are fixed...
Who said anything about adjusting it?
The first step is to see how far out of alignment it is.
I can get mine checked for about £13 so shouldn't be expensive.

Hi steven go to heath tyres in maesycoed Rd .. I had mine done there no problem ..£23 and they keep it on computor for any further adjustments that might be needed

Hi steven
i went to both, and heath tyres ended up doing it, and a brilliant job they did
i thought the computer system was quite cool, but i dont think there was much adjustment done on the rear, however i was too busy reading the newspaper so didnt pay attention to the work
i paid £29 because i was out by a lot and the tie rod end bolts were seized and it was a bugger to do. took them 40 mins to do.
but yes, 4 wheel laser alignment is a must, and if your local, heath tyres are the bees knees :slayer:

Glad to see that you are satisfied with P7.
My stilo seems to have worn the drivers side tyre a lot more on the inside edge than the pasenger tyre. After reading this im thinking its probably the drivers side track rod end has gone?
I only baught it a few days agi and when checking the tyres closer yesterday i noticed the front drivers side tyre is bald on the very inside edge, but the rest of the tyres has lots of tread left. However the passeneger one is worn normally.
I did notice that that tyre onl had 20 psi in, but would have thought it would have worn on the outside edge also if it had benn run that soft for anytime.
Ive now swapped my wheels front to back to monitor the tyre wear.
So track rod end then??

I'd think it far more likely someone has just changed the wheel recently - which means you don't really have any history.
Well worth having an alignment check done and if out then I'd recommend 0° Toe (as said earlier in thread)
Both front tyres (now swapped to the rear) are the same age and make, only one has worn more on the inside edge than the other
Im taking the car to a garage next week for a couple of things it needs so ill ask them to check it out.
Thanks for the replies

Stilo JTD Tyre Wear
I've posted a message on here before about excessive inner front tyre wear on my '02 5dr Stilo JTD.
I've had the tracking and camber checked and the tracking was out a tiny bit, but the camber is fine.
Anyway I'm getting vibration in the cabin and through the steering.
It gets really noticeable above 50 and seems to be worse in corners.
The weird thing is sometimes I can break and the steering is fine, other times I get a lot of shaking in the steering.
Now I'm thinking I'm going to replace the track rod ends and drop links, but my brother suggested it could be the sub frame.
Could someone tell me what the symptoms of a knackered sub frame are?
Thanks
Steve

Re: Stilo JTD Tyre Wear
Personally I've never come across it on here before new one to me..I think you need to get all the steering joints/lower arms etc checked over and the rack as well for ware..if the rack has got ware the tracking will be out what ever you try ..
Bulitin was issued for lower arms [44.01.03] is the bullitin number if thats any help to you..

Re: Stilo JTD Tyre Wear
The car has 2 new suspension arms, 2 new monroe shock absorbers and new brake disks and pads. I had 4 new avon ZZ3's and the car was 95% sorted for a while but the shaking has come back. The front tyres were knackered in about 6-7K miles and I don't drive that quickly.
I've not replaced the worn tyres yet, I swapped them to the back to see what it would do and feels the same.
I had a tempra years ago that did this, a vibration I just couldn't sort.
The ball joints were badly corroded so I'm wondering if the track rod ends and drop links are in as sorry a state.
