1996 GMC Suburban, K2500, 4X4, 3/4 Ton, 7.4LT engine.
Thinking of putting new front rotors, but I read somewhere this is not
an easy job, and that some suspension parts must be removed before the
rotors can be pulled out..
Is there any truth to this?
If this is like my 2000 K2500 P/U (old body style), then yes, the job was
much easier by simply removing the whole steering knuckle from the truck.
Undo the upper and lower ball joints, undo the tie rod end, a couple of good
whacks with a heavy hammer on the side of the point where the ball joints
enter the knuckle is all that is needed to get them free, DO NOT hit the
ball joint or tie rod studs themselves, you will mushroom the stud and be in
for some real problems then. Remove the knuckle assembly, pound out the
wheel studs, use a brass drift, (spin the rotor as you puond them out, so
they don't get stuck behind the rotor). Press the hub from the bearing,
remove the rotor. Clean some of the old grease off and regrease, DO NOT let
any dirt or rust get into the bearings.Reverse to reinstall. These things
are very heavy, it helps to have two people to lift the knuckle back in
place. DO NOT hit on the CV joint to try to reinstall, you may damage the
boot! I found that whatever position the CV shaft lays in when the knuckle
comes off, that is the position it will go back together the easiest. An
extra floor jack under the lower control arm helps during the reinstall.
There are some other steps obviously, like remove the caliper, undo the ABS
sensor, straighten the dust sheild after reinstall, etc.. Don't bother
cleaning the rotor until it is reinstalled on the truck, some good CRC brake
clean and a CLEAN cloth. If done this way you can probably do the job in a
couple of hours.
you'll need to remove the nut in the center of the rotor and slide the axle
shaft out. To do this, you need to unbolt the upper ball joint and separate
the upper control arm from the spindle (after you remove the caliper).
Remove the four (4) bolts on the back side and the hub and rotor assembly
will come off. Knock out all the studs and the rotor will separate. Then
you're in business!
Not a bad job, just make sure you are careful to remove all the dirt/sand
from the hub assembly and around the seal on the spindle upon reassembly.
Did I remember everything?
Not that I know of....and I've done plenty of these. You simply
have to unbolt the rotor and wheel bearing hub as an assembly
from the knuckle, and remove the axle shaft nut. You do "not"
have to remove the axle shaft itself....just slide the rotor assembly
off the shaft and out of the knuckle...making sure that you are
careful with the speed sensor wiring. Once the assembly is
out, you remove the wheel studs and the rotor will separate
from the wheel bearing assembly. Note: when you are
pounding out the wheel studs, be very careful that you don't
wack off the speed sensor as it sits back behind the wheel
Some other posters mention disconnecting ball joints..etc.
Go there if you want a lot of extra work, but it's not
