i just found during winter teardown that my rear end housing is bent not visibly but it is toe'ed out about 3/4 inch any ideas on correcting this problem short of buying a new 375 dollar housing i know you can heat the long side and gain some with shrinkage. let me know , thanks in advance. jl

I have seen an adapter thats slides over the bearing snout on the tube and then use a potra-power to straighten the tube. I thought Coleman Racing Products made it but I can't find it in their catalog, i'll keep looking though.

i think afco makes a rear end straightener for use with a port-a-power.

If it's a floater housing, the chassis shops around here can remove the bent tube and replace it. I've had mine done a couple times. $100 per, if I remember right.

Yep, that's where it was, just seen it on their on-line catalog. Said for wide 5 tubes though, $84.00.

Since you're in the mod section I'll assume you're talking about a 9". Those afco units are for the wide 5.
What I do is remove gear set, and put wheels and tires on the rearend. I put it on my grain scales so that I can fully rotate the rear without pullbar mount hitting the floor. I put a dial indicator on the scale upright to measure and find exactly there the tube is do this by rotating the rear and seeing the wheel wobble and dial indicator read the changes. To move the tube forward, heat the bend red hot with a rosebud torch. About 2" circle is good. Now quence it with cold water via a garden hose. It must be cooled as fast as possible to move it the most. Repeat along tube as necessary. Once you have "treated" an area of a tube, it won't move if repeated again, so move to area down the tube.rotate rear to see if fixed.You get wet but this method works.

I run a shop where we have a jig to straighten all types of housings. I recommend that you don't heat the housing at all!!!! It will make the housing weak & take the spring out of the tubes. we straighten rear housings for $150.00. if interested lmk.any straightening must be done COLD!!! Good luck.
