I claim: 1. A device for aligning with a king pin on a trailer, the device comprising: (a) a first bar having a first coupler at one end thereof; (b) a second bar, co-linear with said first bar, having a second coupler at one end thereof; (c) first and second couplers adapted for attachment to said

I claim: 1. A device for aligning with a king pin on a trailer, the device comprising: (a) a first bar having a first coupler at one end thereof; (b) a second bar, co-linear with said first bar, having a second coupler at one end thereof; (c) first and second couplers adapted for attachment to said king pin; (d) each bar having a projection therefrom for aligning said bars on said trailer when said couplers are attached to said king pin; and (e) first and second sleeves carrying squaring means; wherein said bars include a key. 2. A device as claimed in claim 1 wherein said sleeves each contain a keyway. 3. A device as claimed in claim 2 wherein said key engages said keyway on said bars to align said squaring means relative thereto. 4. A device as claimed in claim 3 wherein such squaring means are displaceable relative said bars. 5. A device as claimed in claim 4 wherein said bars each include an attachment. 6. A device as claimed in claim 5 further including means for stabilizing said device relative said trailer. 7. A device as claimed in claim 6 further including measured rods adapted for connection to said attachment on each said bar and disposed towards an axle of the trailer. 8. A device as claimed in claim 7 including a plurality of measured rods. 9. A device as claimed in claim 8 further including a first and second housing for attachment to each end of said axle respectively, said housing including an axle extender. 10. A device as claimed in claim 9 wherein said housing includes a window for viewing said axle extender contacting said axle. 11. A method of aligning at least one axle on a trailer having a king pin, comprising: (a) placing a first bar having a first coupler at a first end thereof under a first side of a trailer adjacent a king pin; (b) placing a second bar, co-linear with said first bar and having a second coupler at a first end thereof, under an opposed second side of the trailer adjacent the king pin; (c) assembling said first and second couplers around said king pin; (d) aligning said first and second bars relative to the trailer so as to extend a second end of each of the first and second bars to either side of the trailer; (e) attaching an axle extender to each side of a first axle; (f) connecting at least one measured rod on each side of said trailer between the second end of each bar and an outer end of each adjacent axle extender; (g) measuring the distance on each side of said trailer between the second end of each bar and an outer end of each adjacent axle extender; and (h) adjusting said axle to substantially equalize the distances between the second end of each bar and an outer end of each adjacent axle extender on each side of the trailer. 12. A method as claimed in claim 11 wherein said axle extenders are removed when said first axle is adjusted. 13. A method as claimed in claim 12 further including means to adjust the distance between a first and second axle. 14. A method as claimed in claim 13 wherein the distance between said first and second axles are measured by a measuring tool having projecting rounded ends adapted to contact a counter sink hole presented by said axles. 15. A method as claimed in claim 14 wherein said distance between said rounded ends on said measuring tool on one side of said trailer is compared with the distance between said rounded ends on said axle on said other side of said trailer.
