I bought a 90 rear axle housing with the intention of putting the axle shafts in my 86 4Runner rear. I noticed that the axle shafts out of the 90 are 1/4" longer than the ones I have. I measured the width of my axle from the backing plate mounting flange to the other flange (since the axle's are out) and it is approx 51.25". I measured the 90 housing and my buddy's 90 truck and it is about 52.00". I know that the 85 and earlier trucks the axle width's were 3" shorter, but I'm only dealing with 3/4" difference. Will putting shafts in a 1/4" longer matter?

I don't have the third in, but I can put it in and see if the axle will slide in and if I have a 1/2" of room in the carrier. If they fit, should I run them?

Could I run one of the shorter ones and one of the longer ones?

Thanks for the help.

 

yeah tye will work fine... axles ar ethe same width 86 to 95 id say..
might just be aftermarket or newer axles taht are little longer for more contact in diff??

did they fit?

 

I believe so, I got one side in to check and it fit. But that seems strange, I assume if they fit its ok to run them. I know I can measure, but my housing being 1/2-3/4" shorter than a 90 short bed truck? Doesn't seem to make sense.

 

my buddy told me it may have to do with the 90 axle having a v6 third member, could that be the case?
