4wd conversion? - Competition Diesel.Com

xrobwheel · 05-15-2023, 07:45 AM

Trying to swap an 06 front axle into a 99 2wd truck. At a glance the radius arm brackets on the 2wd and 4wd look the same but I am unsure. Need to figure out if I need to buy them too. The coil buckets look very similar but dont know about them either.

The swap is pretty straight forward. 04 and older you need to remove the existing brackets and replace with 05+ radius arm brackets. You will need a 3/8" spacer to get the holes to line up.

Here are the parts you need:
entire 4x4 axle assembly including trac bar, all steering components, radius arms & coil springs.
05-07 track bar bracket-will require frame drilling (08-10 wont work)
05+ coil buckets (holes are in your frame already-just need to be reamed),
Steering gear w/ pitman arm from 05+ 4x4,
manual shift transfer case,
tear down the transmission & reassemble with a 4wd tailshaft to accept the transfer case,
4x4 front & rear driveshafts,

Also, the 05+ axles are different widths so you will either have to run wheel spacers in the rear to make it match or swap the back axle as well (i recommend this as the brakes are better and makes it less confusing when buying wear parts) That being said, you will have to add the vss sensor to the donor rear axle.
