rotors for 89 D 250

[Big Don]

Guys,



Ol' Blue was needing front brakes, so... pulled the brakes and the rotors can't be turned anymore. Went to buy some for an 89 D250 with 4000lb. front axle. The frist set they showed me (hub and rotor 1 pc. ) are not the right ones. Then they showed me a rotor that has holes in it. You have to press the studs out of the hub and replace the rotor. They were listed for a 1 ton truck. I got home, pressed the studs out and went to reassemble and the new rotors have 9/16" holes in them where as my old ones had 3/4" holes. I called several places and no one offers the rotors with 3/4 holes. Can yall help or am I going to have to go back to the Dodge dealer and get the shaft???





thanks

i have bought several sets of rotors for my 92 at Auto Zone. They work fine.

Got mine at NAPA, no problems other than the studs were a pain in the A** to get out. The new studs were a little different and I had trouble with them hitting the back of the aftermarket wheels. Had to ream out the back of the holes in the wheels so the wheels would sit flat on the face of the hub. Make sure you check for clearance if you replace them.

Guys,



I have called autozone and even checked with Napa again and they do not offer these rotors with 3/4" holes in them. Can someone verify that the rotors they bought had the 3/4" holes in them??? I have a truck up on blocks now cause I cannot find the correct parts for it.



thanks

Guys,



Had a thought. What if I just drill the holes out to 3/4"??? Do you think it will work okay?? Has anyone else replace the rotors on an 89 or 90??? I am trying to figure out why their is a difference in my truck and the later trucks.





thanks

Don

I'd eyeball the two rotors and make sure there was enough meat to support the stud after enlarging the hole(s). If there is, then you probably want to find a buddy with a mill 'cause to do it right the rotors should be set up to pick up the existing holes, which should be drilled just under sized then reamed to the final dimn. Drills are notorious for cutting slightly oversized and here ain't where you want to take a chance on being "close enough". I know it sounds like a pain but if theres no other way to go then how much is your butt worth.

Hope this helps, Jones
