Thread: slotted swivel hubs

the long weekend provided enough time to get in the shed and play landy. so I wipped the swivel hubs off and slotted the holes. my county has 130mm bumpstop clearance and the castor angle was all wrong, after reading Discowhites fix for the castor correction I thought i would give it a go. I marked out the flange where the new hole had to go and center punched the the new position, I then drilled the holes out starting with a pilot drill then going up 4 drill sizers at a time. I then used a die grinder to join the two holes up. Now to how much to rotate the hub, first measure the curcumfirance of the flange which was 383mm then divide it by 360 degrees,=1.06mm. this measurment is equal to 1 degree. Now stock castor is +3 degrees with approx 70mm bumpstop clearance so that is a differance of 60mm or 2.4" for me. I have read that for every 1/2" of lift you loose 1 degree of castor so multiply 2.4 by 2 and this gives you the degress lost by the lift= 4.8 degrees, take 4.8 from the factory +3 degress and you have -1.8. to correct this you multiply 4.8 degrees by 1.06 to give us the distance to rotate = 5.088mm. so fit the hub and make a referance mark on both flanges on the hub and the axle housing(best done before removing from the vehicle) now fit two bolts on opposing sides not to tight though and use a steel rule to measure your adjustment nip the bolts up and check your measurments again, when happy referance mark the new position on the housing. then continue fitting the cv and hub assembly as per normal.

Hey Peachey...

It's like people whose shoulders dislocate all the time asking someone who has had the op to fix.

If you're needing to ask the question you need to do it.

One of the all time best things I did to mine, which has a 2 and a little bit" lift.

Love your truck BTW.

cheers, DL
