	Always tighten suspension bolts up with WoW (weight on wheels), esp. rubber jointed ones like top and bottom wishbones and shock absorber bolts; a 2nd lightweight trolley jack comes in handy at times like this.

	With independent suspension rear-wheel drive vehicles it is important that the rear toe and camber angles are checked as well. The toe-in especially, as toe-out can cause instability! T25s have very slight toe-in (10'), but the +/- tolerances allow a smidge of toe-out.

	~~Here's one set of figures from '''Nigel in SA''' for a Syncro~~

	~~I have 235/75/15 tyres. Alignment specs used at my alignment shop are below~~
	~~(with my syncro's actual values in brackets):~~

	~~'''FRONT'''~~

	~~Caster: 4.41 to 4.91 (L=5.00, R=4.01)~~

	~~Camber: 0.66 to -0.40 (L=0.18, R=0.08)~~

	~~Toe: no spec (L=-0.2, R=-0.2)~~

	~~'''REAR'''~~

	~~Caster: no spec~~

	~~Camber: -0.42 to 0.25 (L=-0.66, R=-0.39)~~

	~~Toe: -0.5 to 1.6 (L=-0.2, R=0.4)~~

	~~Regards~~
