Hi Looking to purchase a 2nd hand yukon to pull my 5000 pound trailer and trying to gather as much info as possible ,Looking at an 07 with 101000miles with a 5.3 engine, Does anyone know how i would go about finding out the axle ratio on this vehicle? owner does not know, thinks its a 355 any help would be greatly appreciated thx jim
Jim, go to compnine.com and put in the VIN, costs a couple of bucks. It will give you the RPO sheet and other information about your prospect vehicles. Look up the G-codes for the axle ratio.
There should be a sticker on the driver's door jamb too showing the GVWR of that particular vehicle as optioned.
A 4-speed Yukon, the short one, with a 5.3 had these specs for towing:
2WD with 3.42 Gear: 6,400 lbs
2WD with 3.73 Gear: 7,500 lbs
4WD with 3.73 Gear: 7,200 lbs
4WD with 4.10 Gears: 8,200 lbs
Don't know what you know about trailering, there are many other factors and weights to consider when towing.
