    I've got a 14 on the way, but I need o get the spill on converting my 90 front 10 bolt over to 8 lugs. What year models or what do I need to get for the front to be 8 lugs. I reviewed all the search stuff and all the crap about 1st and 2nd version. Can someone clarify what I need?

    Thanks.

    Alrighty, I'll do my best. I did this last thursday. I took a 10 bolt from an 87 Blazer and the caliper brackets, spindles, and bearing hub's from a 74 Dana 44. The ONLY snag I ran into was that the studs on the 10 bolt knuckle were an 1/8" too long and had to be lopped off.

    Really, If you've read all the stuff, includeing the article on the main page, then lay into it. You could prob. get by with your spindles and caliper brackets, but just to be on the safe side, I didn't.

    Could I just order new hubs and rotors with 8 lugs?
    I replaced the 10 bolt 6 lug hubs and rotors for real cheap when I first got the truck. So...... in theory?????

    Sure. The conversion for mine really can't be broken down in price, I got the front 44 for basically nothing then robbed the spindles and [censored] off of it. From the prices that I can remember, it was about $180-200 for the hubs and rotors apiece. Then the bearing and misc [censored] ran me about $60 or so. I got alot of my parts dicounted due to the amount of business I take to the local parts house. The conversion took me all of a couple or hours tops. I used the same calipers from my 89 on the 74 brackets. IF IT WERE ME, I would buy parts for an 87 3/4 ton 10 Bolt front. That would pretty well guaruntee you the right parts. Do some shopping on the parts, call a couple different places local, then call Parts Mike, or Border Parts. Someplace like that.

    After looking at the article in the Tech section, I'll through in my $0.02 about some of that. The caliper brackets that were used in that conversion include the dustshield on them. Again, If it were up to me, I'd try and find brackets without those or figure out some way to take them off, they are bad about gathering mud and rocks and damaging the rotor. My 44 didn't have them, so I got lucky.

    HTH, if you got more ?'s lemme know,

    The things you will need are the backing plates, rotors, and hub assembly. I bought my rotors and hub assembly brand new from o'reilly's about a year ago. Every junk yard wanted more then they did, plus these have lifetime warranties which i have used on a rotor and hub assembly. Sand got in through a bad seal and ate my roller bearings for lunch and destroyed it. Even had to replace the spindle. Your hub won't have to be replaced. Brakes should bolt right up. Didn't have any problem with mine. Tell me if you got anymore questions. Later - Doug

    Its been a while since I've had the front tires off. I was thinking the hub was the part that held the stud?????
    So how would I not need a different hub. Aw hell I'll oull the [censored] off and take it all to the store and compare them all on the counter. They love me down there!!!!!

    He's prb. talking about the locking hub. Your thinking of the bearing hub. Keep checking. I'm getting ready to qoute a 6-8 lug conversion for a guy here in town, so I know the parts house can get the stuff for you. Try a couple different parts places

    If I understand you correctly, I dont care about the pricing if you have to call around. I just need the part numbers to shorten the dumb ass parts counter geeks look up time.

    Thanks Kyle. I may have some stuff coming my way from

    The part number I have for the front hub is a brakebest part # 81-61708. This runs about $55.00 my price per hub assembly

    Hope this helps.
