How big of a jack do I need to lift a Freightliner Columbia 2006, 20ton or 30ton???

I use a 20 ton to lift my 04 columbia all the time with no issues.

 

A 10 ten will lift the whole front end without issue so it will be plenty big enough for one side at a time.

 

Don't forget jack stands. I stack a piling of foot long 4x4s under the front axle - each side - works better on the gravel driveway.

 

i would use a 20-22 ton bottle jack and some wood 4x4 or 6x6 blocks to raise it. better to go bigger if your ever hooked up to a load and need to do work back there this will come in happy.

 

Or pull in to a shop and have them lift it for a couple of bucks and check things.

 

I have two, one 15 t, other 20 t. 30 ton you need if you tow low boy with overload.

 

If it's empty, I was able to lift each corner with a 4-ton jack.

You only have to lift 1/2 of whatever your axle weighs.

Fully loaded, I wouldn't use less than a 10-ton for a tandem.

 

A 10 ton would work. A legally loaded steer axle doesn't exceed 12,000 lbs. (6 tons). So, a 10 ton jack (20,000 lbs, capacity) should pick up the entire front end without a problem. A 5 ton would pick up an empty front axle.
