Re: can i change a leaf spring rear axle to a coil spring rear axle
You can if you're good at cutting & welding. But being that you're asking these questions, I'd suspect you're not that experienced as a fabricator.
My main concerns would be; can you cut the coil spring perches off cleanly enough to have a good piece to weld back on. Do you know how to set your pinion angle correctly when installing the perches? And do you know to not weld them on in one continuous weld as that might distort the axle tube? |

Re: can i change a leaf spring rear axle to a coil spring rear axle
They are probably different lengths. The 71-72's were widerr to match the wider track of the 5 lug disc brakes.
I would just use the 5 lug leaf rear, if it is in good shape, or wait for a 5 lug coil rear...they are pretty common. Last edited by Skirkpat; 05-31-2009 at 01:57 PM. |

If your friend that offered to do the work has the skills, setting the pinion shouldn't be a problem. I've not personally done this particular swap, but take your coil spring rear out and set it on some jack stands or whatever and note the pinion angle (using an angle finder) with the coil spring pads setting on something firm. Make notes, pictures or whatever and then cut the pads off. After cutting the leaf spring pads off of the other rear end, set it on your coil spring pads at the same angle and tack them. Does that make sense? Last edited by slosteve; 05-31-2009 at 02:35 PM. |

Re: can i change a leaf spring rear axle to a coil spring rear axle
I'm doing this swap right now. I just cut the old leaf springs pads off and cleaned the axle tube. I bought new coil spring type axle saddles from ECE for cheap. Match the pinion angle of the original rearend and weld the saddles on tight.
I am running a super track bar for a panhard since the leaf type of rear doesn't have the place on it for the track bar to bolt to.
