    New suspension and alignment difficulties

    I bought a 2016 NX Pajero (ex-copper) earlier this year and was aware the alignment was a bit out due to wear on the outer LS front tyre and pulling to the left a bit. I'd just been sitting on it for a few months due to not doing many miles and planning a suspension upgrade.

    Fast forward to now; I fitted a 2" Bilstein/Lovell's lift with extra-heavy duty front and heavy duty "100-300kg" rear springs (with much swearing, but managed). Naturally due to replacing well-used factory springs/shocks with fresh heavy duty variants there was a BIG change in ride height (9-9.5cm both ends) with excessive positive camber at the rear and riding terribly. Gave it a half dozen short trips to settle in a little (new ride height 1-3cm less) and got a wheel alignment done last week at the local Kmart (my usual mechanic doesn't do wheel alignments and it was $69).

    First time round they adjusted front toe to within spec (from around +19mm!) although I think they left front camber unchanged (just out of spec, see pic). The rear axle as expected had significant positive camber but was left unchanged. Of course I was home by the time I reviewed the readings; at least I got the print-out.

    So I took it back for a second go mainly regarding the rear camber and they were able to improve that significantly (I gather it's often not possible to get the rear quite back into spec post-2" lift). They also had another go at the front but weren't able to get the RH within spec.

    So there's still a bit of a pull to the left which is consistent with the print-out. My question is, how concerned should I be about this? Just accept it and rotate the tyres, or do something about it? Also, it's on the driver side; is it going to get better or worse with a driver in the seat?

    Interestingly, on the 'before' spec on the second alignment it is significantly further out of spec than on the 'after' spec on the first alignment - equipment variance? User error? Someone sat in the driver's seat on one occasion?

    Thanks for your thoughts.

    I'm no expert, but I'd like to know why there are no figures for caster or king pin angle - if you're having steering issues.

    These figures aren't included in the standard format to make up space. They're included because they're important - when you have a problem.

    For 90%+ wheel alignments, toe is all that is required, and camber is occasionally an issue. So not enough "wheel aligners" understand the importance of caster or king pin angle, much less how to interpret numbers out of spec and how to correct them.

    If you're not happy with the way your Paj is driving, go back and ask for all the blanks to be filled in. If KMart can't understand what the report means, shop it around until you find somebody who can.

      Yes it's probably a case of 'you get what you pay for'. I think that's good advice.

        Just recently upgraded my suspension with ultimate suspension
        HD front and raised standard rear.
        Had new tyres fitted and alignment done.
        Made sure it had 80kg approx weight in rear when they did it.
        Drives great and no issues at all.
        I have been in the trade for 30 odd years so it helps.
        I wouldn't use Kmart though.

          Ultimate Suspension do all their alignments at Tyrepower just down the road, I had my Paj done there and drives as straight, apparently that tyrepower specialise in 4wds.

            Update: I had it realigned at Tyrepower who have apparently just got a new machine. Anyway the toe, camber and castor were all out although they were most surprised by the amount of toe out. It's unclear why the initial readings are so different from the Kmart final readings. In fact the setback is even measured in degrees instead of mm. Perhaps a machine/operator difference..

            Although the rear camber is marginally outside spec on one side it now drives straight which is I think the main thing.

              Hi all,

              On this topic, I had a 2" lift installed recently on a 2007 NS. You should definitely receive within spec values for individual toe, camber, castor and KPI for front and rear axel. In this case, everything on the alignment was considered normal except rear camber, which was +1.31 and +0.58.

              I was told that the camber adjusters had seized, which is a good reason for the mechanic to leave something unadjusted.

              However, these are very expensive to replace on a Pajero because of labour (I was quoted $650 from the place that installed the kit) as they are on most cars that have them.

              Does anyone know what is within spec for these cars given they're an IFS system, and will the above mentioned rear camber specs flog bearings or damage parts?

              From what I hear I'm not the only one pondering the actual meaning of alignment results...

              Cheers!

              Ben
