So, I collected my car last night from having a replacement driver side complete driveshaft and passenger side rear wheel hub fitted.

I had previously had a Fast Road Set-up applied to it, rather mild settings, nothing too aggressive (I have the readout if it helps).

I requested to have the geo checked while the car is there just for good measure. Everything was fine, no need for adjustment. I believe this was carried out after the parts where fitted.

Brand new tyres too fitted about 80 miles ago (452's on V2 OEM 17"s).

Everything feels fine on the way home until I hit the motorway.

Under hard acceleration, the car sort of drives to the right a bit, not so much pulls, as if it's the front wheels, but sort of leans over to the right which you need to correct, (very slightly).

Also, manoeuvring at motorway speeds (changing lanes) feels very skitty, almost twitchy and almost on the edge. Very far from the planted solid feeling I was used to.

Needless to say, this far from ideal and reduces confidence in the car.

Two questions;

Firstly, would having these parts changed affect the geo ?? Without touching the camber adjusters ??

Secondly, to my eyes, the passenger side rear wheel is pushing significantly more - camber than the driver, I may be wrong here as it was fading light, but would this result in the above symptoms ??

I'm going to call my tuner today and have a chat, who I'm sure will sort it out, but I'm keen to listen to anyone that may have an idea as to WTF is going on !!

I reckon they haven't bothered with the geo afterwards, or looked at it and thought it'll be alright..

Fitting hubs etc takes it all apart so it will effect the geo

I totaly agree Did they give you a printout with the geo measurements?

Hmmm, that would be your (and my initial thought) but I doubt that.

Now this I wasn't sure of, if that is the case, then hopefully it's an easy fix of just getting it reset, however, I'd be shocked if this was overlooked and not noted.

Have to get it sorted soon I've got a Spa track day in April !!

No, as no adjustments were made.

[unclefester]

How?

There is almost no way you could put all that back together and retain the original Geo although there is no hub adjustment so unless they moved something when removing the old hub it 'should' go back almost within tolerance.

What about drive shaft bearings, is it possible that one is now more worn than the other and it's messing with the diff? Have they tightened the balljoints up properly? What about droplinks?

[WinFreak]

I reckon their 'within spec' is a lot different than ours

Did you give them your print of the last geo adjustment?

Still they should have given you a printout of the current Geo setup. They did all the work to put the car in a Geo maschine without making a printout? I believe they didn't bother at all plus i agree with the hub removal and the Geo with the above members.

[Suits]

Alright guys, all interesting stuff.

I'm going to call them soon and have a chat about the possibility of the Geo being overlooked.

I'd much rather that be the case than anything else wearing unevenly or anything like that.

[Suits]

Well I'm booked back down there on Tuesday to find out what's wrong and get it sorted.

Very appologetic and was keen to get me back ASAP to get it sorted out.

The geo was checked, and all was in range, but it will be checked again.

I'll report back with what was discovered.

[Suits]

All sorted .

It appears that altering the hub, DOES affect the geo, even though the adjusters weren't touched. Perhaps it's newer designed hub that has been adjusted slightly over the older ones, or, it's bent. lol.

This is what it was....(no wonder it was driving like a pig)



This is what it was set back too.



Nice. All fixed and drives wonderfully.

I'm quite disgusted at how they let you drive away with it like that first time around. I hope you got a free air freshener for your troubles

Yeah, far from my ideal, it's a 170 mile round trip, but the owner is a good mate and helped me on many a (Oh Shit !) occasion over the many years I been taking my Honda's there.

Just happy its sorted to be honest and I can prepare for Spa again.

[unclefester]

Probably moved stuff getting balljoints out.
Who knows but numbers look much happier as are you

[martin j]

I take it that the machine doesn't agree with the 2degrees of camber so it shows in red?

[unclefester]

No ... red is negative and green is positive, that's all?

No mate, it turns green if the readings are in a tolerable level, ie, close enough for road driving.

But the before shows red for a + and - front camber
My understanding is red is out side the database settings for that car ie Hondas UK settings
Glad it was just a geo reset though!

Clearly having a thicko moment - it can't have been checked the first time though, at least not properly ... maybe it just 'looked' right. I'd also bet money that someone who didn't know the car or how to drive wouldn't have noticed the difference on a short test drive.

To be fair, the issues were only noticeable at motorway speeds and cruising, or changing lanes.

I even took the car out on a test drive and it felt 'alright' on the little link B roads. Although as soon as I got on the motorway it was terrible.

Still, shocking to let a car go out like that really.

[unclefester]

It's just possible that your old hub was bent or distorted and the replacement one wasn't - hence the Geo being out. If the old Geo adjustment was based around a dodgy hub that might explain the change.

Or that, yes.

There are a few reasons that could explain it, but to be honest, I don't care anymore, I'm just happty it's fixed .

[razzele]

Strangely enough the service instructions are to check rear alignment after changing driveshafts alone.

It maybe placebo effect but I was sure that I could feel a misalignment after changing my shafts.

[mr-pitts]

Unless they removed the lower wishbones/toearms, which you don't have to to replace the shafts, I don't see how the Geo could have changed.

[Nick Graves]

You do to replace the HUB though!

Also you can measure twice in a row & get different results. But that rear toe was lethal! Fail.
