Help Needed! Four wheel tracking/alignment of AWD 2007 Alph

[PalePisces90]

Afternoon everyone!

 

Just had 4 new tyres fitted to my 2007 AWD Alphard and now it needs to be re-tracked.

 

Unfortunately, the place which previously carried out a re-alignment of the front wheels only, are now saying that they do not have sufficient info to carry out full four wheel tracking on this particular vehicle.  It's an MNH15W (model code).

 

Does anybody know of somewhere relatively close to Cheltenham where I can get this carried out, please?

 

Just an added wrinkle on top,  my car is lowered and has trouble getting onto some garage ramps. Ideally it needs one the ground level turntable types, but any recommendations are welcome and I can make inquiries.

 

Thank you in advance for your help.

Further to my earlier post, I have rooted around on the forum and found the following link:

 

http://www.jltechno.com/en/alignment_specs.php?brand=Toyota&ModelName=Alphard/Vellfire:H10 Series:MNH15W&ModelID=610366

 

This looks to be the info I am after but would just like some reassurance from others in the know if possible, please.

 

If this is right, I can refer this info to my local garage and see what they say.

 

Thanks again.

Hi George,

 

Sorry, don't know about tracking specialists close to you in Cheltenham.

 

As you'll probably know, the rear axle is fixed, so there are no adjustments to make and, in the absence of any specific problem, it may be that a front alignment check is sufficient. That said, 4-wheel alignment may still be worth doing - we had a problem with steering pulling constantly to the left regardless of road camber, the 4-wheel check showed that alignment on NSR rear was out, due to a poorly assembled wheel bearing retainer - 2 of the 4 nuts were missing so the leading edge of the wheel was facing slightly outwards.

 

Alignment figures from previous posts on the forum have varied:

 

Here are the  2007 Alphard figures from the jltechno lookup:

Alternatively, our wheel alignment specialist found the following figures for 2002-07 Alphard, after searching Japanese data. They're a more extensive set of figures, but for some values the tolerance range is narrower than the figures above:

FR Caster	+1.40		+3.10
FL SAI	+10.05		+11.35
FR SAI	+10.05		+11.35
FL Included Angle   FR Included Angle   Front Cross Camber	+8.40   +8.40   -0.45		+11.40   +11.40   +0.45
Front Cross Caster	-0.45		+0.45
Rear Total Toe	-0.15		+0.15
RL Toe	-0.08		+0.08
RR Toe	-0.08		+0.08
RL Camber	-2.0		-1.0
RR Camber	-2.0		-1.0

We chose to go with the figures that had less tolerance, on the basis that we'd be conforming with both sets of figures.

 

Good luck with your search...
