Ok, I have this post somewhere else but realized it could be in the wrong place, so I am starting this new thread. Apologies for duplications or for using wrong forums.

I picked up a used 2007 MS6 (mileage is 59,000kms) today and I drove about 60-70kms . I know it's not that much to tell whether there are issues or not but I noticed (as I did prior to buying the car) that there tends to be a slight pull to the right. The steering wheel was slightly off center a few days ago but that was fixed when i picked up the car today.
FIrst I am not even sure if it is an issue or not because the pull to the right is not substantial and if I have on hand on the wheel the car goes straight without any difficulty. If I let go, depending on the road surface, it tends to go to the right. Ok I understand roads tend to be crowed for drainage of water but has anybody experienced that with their MS6 or is it just me?

I asked a friend to drive my honda accord with me following behind and we had radios so we could communicate. Basically I followed him with me in the MS6 and coordinated to letting go of the wheel to see if both cars would pull to the right the same way. The result is that most of the time both cars would pull to the right except the MS6 does it faster (i.e. takes less time to do it). THe honda has cheaper 16" winter tires and the MS6 has the Nokian Hakkapalleti winter tires 17". THe nokians are also 225 whereas the honda has 205s I believe. Would the MS6 pull "faster" because the steering is generally stiffer than in the Accord? (i.e. once the wheels are slightly offset maybe due to uneven road surface, they tend to be "stuck" in that position unless corrected by the driver). Or maybe it's the width of the tires that are making the difference in how fast the cars will be pulled?

I am thinking about taking the car back to the dealer and ask them to check again. They apparently aligned the wheels so assuming they've done it correctly, it shouldn't be the alignment.

Again, anybody know is this is an actual issue or if it is normal? Apparently I've been reading on this forum that MAzda 6 cars have had "issues" with the pull to the right and there was a TSB for M6 but I don't know if that included the MS6 as well.

Other than that, everything else in the car seems to be working fine. I have to say, What a great looking car!

i would say it prolly needs a better wheel alignment. mine doesn't pull and its bone stock and roads around here suck ! lol

ask them for a print out of alignment if they use that type of equipment. my place gives me a digital printout.

Hmm... I was going to take mine in for a wheel alignment next week, but now reading this I'm wondering if I have the same issue.

My car definitely pulls to the right, enough where I need to keep the wheel pulled slightly to the left.

I'm still going to probably take it in for alignment since it's been almost two years.

We'll see what happens.

Think this is covered under the terms of the CPO?

Ok, so I got the car back from the dealership and it looks like the issue is more or less fixed. I say more or less because I can't really tell anymore whether it is road crown of the car that is pulling to the right. In any cae, my honda accord also pulls to the right a bit and I believe it is due to the road.

But the MS6 definitely pulls less than yesterday and is more stable. Unfortunately I have not been able to talk to the service manager who had already left when Ipicked up the car. I will call him tomorrow and ask him what he did and give you guys the feedback.

Mine used to pull hard left when I first got it. A couple alignments helped, but it still pulled left. Got the SPC BJ's and some negative camber, and I'm sitting straight at a buck :) ..er, assuming the road it dead flat. The MS6 will follow a slight pitch on the highway. So, if you were in the 'fast' lane, expect the car to want to drift to the divider.... awd is more sensitive to road pitch.

I'd try the BJ's first, hopefully you won't need new control arms. Bova, were those expensive?

Do you know what the difference between original control arms and the TSB replacement. Dealer did TSB at 8K miles because fronts were feather edging o/s edges from new. Car never has pulled, but does not track straight either. Guess they did minimum toe in because of my complaint.

There are 4 optional control arms. 2 (1 left and 1 right) with the bushings offset to add 0.4 deg caster and 2 (1 left and 1 right) with bushings offset to subtract 0.4 deg caster.

The dealership said they have to change the control arm as the car is now making a tumping/rattling noise when I drive. Apparently the alignment (car was pulling tothe right) they did was such that the control arm doesn't "fit" properly anymore as it has no play in it (apologies for the lack of techincal terms. I am not into mechanics). I have to wait until next Monday or tuesday as they are closed for the christmas period.

Fordza 1, you seem to know quite a bit about this. Does it make sense when they say that it is the control arm that is making that noise and that it has to be replaced? I saw on this forum that there was a TSB for cars pulling ot the right and that included changing the control arm. What I couldn't figure out is whether it included the MS6 or just the M6.

Thanks

Yeah, the TSB doesn't specifically list the Speed6, but the chassis parts are all the same. The TSB tells them to loosen the entire subframe and/or lower control arms and reposition, so indeed things may not fit "right" afterwards. I cringe when the dealer goons do anything to folks cars. Hopefull they will set you up correctly and the car should drive just fine...

Ok, looks like they fixed the issue. At least, I can't really tell whether the car pulls to the right or not.

Basically, they had to change the passenger side lower control arm and do another realignment (within specs). Now the car seems to be going pretty much straight (the roads are not flat here so it's hard to tell). But concerning this issue, I am fairly happy about it. I wonder what caused it and if the previous owner(s) ever noticed that???<_<

I know my explanation is not very technical and not very detailed but I hope it will at least give some options to people who are having the same issue.

Oh and I forgot to mention that I had a noise (tumping/rattling) coming from the front of the car. I was told it was due to the control arm (the one that was changed) not "fitting" properly anymore following a first alignment. I can't hear any noise anymore now. I guess it was indeed the control arm that was causing the issues.

Finally had a chance to get mine in for an alignment and everything checked out in spec, no alignment was needed.

Car still pulls to the right... fearing it's the control arm.

I can deal with it for now until I have a minute to have someone look at it.

After an alignment and replacement of lower passenger control arm, the car drives much better (i.e more straight).

There is still a very slight pull to the right (the kind that you cannot feel at all when driving but that you may sometimes notice if you let go of the steering wheel and depending on road conditions). Basically, one finger on the steering wheel is normally enough to get the car going straight.

I wonder (need expert advice here) if the stiffer suspension/ride, bigger wheels, high tire pressure, as well as AWD does not contribute to "accentuate" any road crown or bumps? Anybody?:)
