Be VERY careful with the information you're getting from RockAuto.com - if I'm right you're looking at the Surtrack/Trackmotive axles - click on the part number in the link and you'll discover that what they have listed as fitting the 1.8 is actually for the 1.6, and what's listed for the 1.6 is for the gen 2s.

Based on Suzuki's part numbers, the front axle housings will interchange which means any difference in the tracks has to be accommodated in the axle lengths, and as far as I'm aware, the 1.6 is the narrowest vehicle, and therefore will have the shortest axle shafts.

Thanks, as always, Fordem. When I get back to the states, I will see where I bought my front axles.  I am pretty sure they are from Autozone.  I am looking at swapping to 930 axles later.

I get back next week in time for the 4th of July, but I will be busy with work for at least a week.  After things slow down, I plan to put my other rear axle on saw horses and attack it with an angle grinder with a wire wheel.  I need to paint it, check the brakes, and prep it for a locker install.
