    O.K. guys and gals,

    I am doing my 8 lug conversion and came across what seems to be unusual. First of all I bought my parts from a guy on the Pirate board and he told me they were all 8 lug 10 bolt stuff. I have a D44 in my 75K5. I installed new ball joints and then proceeded to install my "new" 8 lug bearing hubs & rotors. By the way if you do this your outer race and bearing may just be the same as the 8lug hubs. At least mine was anyways. In order to get my 8X15 rims with 3.5" backspacing to fit I had to do some extreme grinding! Looks like some metal may have to be welded on the inside of my caliper bracket to give some strength back to it. I've heard of D60's being ground this bad to fit a 15" rim but never heard of anyone having to grind to convert a D44.

    Has anyone else had to do this??????????

    I know i had to grind a lot, not enough to lessen the strength but it was a lot. I had to grind the backing plate also.

    I ground so much off the backing plate that the tabs supporting the sides of the caliper fell off. They were so thin due to the amount of grinding that I just bent them off. So far no problems. I check for abnormal wear on the rotors and for loosened bolts. So far so good (5 months). If I were to do it again I'd try to heat the backing plate and pound the hell out of it until the rim fit.

    I think Triaged just got some 15x10s with 3.5" of back space and he only had to do minimal grinding.I wonder what the dif is between different 8 lug set ups be it 10 bolt or D44?

    Not sure that there is any diff between the 10 and D44. I do have the tranny in, the rear shock mounts and the rear cross member done though. The Front conversion should be done this week sometime. I can't wait to get out and try all my new stuff!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Oh the winch will probably take a couple weeks to get installed. I need to take it apart and clean and lube everything up then fabricate a new bumper to mount it to.

    I had to do that much grinding to fit the 15's on my 8 lug Dana 44...it's been a year now and no problems though. I might still re-ienforce that area of the backing plate though.
