Spring perch welding

[Stinky]

On my '86 2wd Nissan PU, I want to change the axle ratio and the easiest way to do it is change the axle. I have an axle from a 4x4 PU...totally dif, but it is slightly beefier and is 10% lower.

The perches are totally dif.

Not a big deal, or is it.

My friends say that the perches need to be very precisely welded on....that they have to be welded on just so. I'm thinking that it ain't no big deal, just put them on and weld them on w/a weld that is similar in size and etc as the factory weld (say 1/8" 7018 or a MIG).

BTW, I am gonna tack it w/my 110V Flux core and the take it to a shop for the final beads.

I am not talking about alignment of the perches. I am talking about the metallurgical bond that is used to affix the perches to the axle.

What do you think?

just a good burn in and you should be fine.

some light duty axles have thin tubes so watch out for wall/tube thickness to not burn threw .

measure your pinion angle now at yoke/flange on rear were drive shaft hooks up . then set new in and match angle the same way you had truck set when old was measured and tac / weld in good .

don't forget shock mounts .

I have welded plenty of perches with a 110v flux core. Nice big welds with good penetration and you won't have any trouble. If you are worried about your weld do a couple passes.
