Well, maybe not a tune, but it's humming. It starts being noticeable
around 20 MPH, does NOT change with engine speed, only with road
speed, and goes away when turning even slightly to the right. Both
diffs have Mobil 1 75W-90 in them. Truck does not pull in either
direction and the front wheels seem solid when lifted, so I don't
think the bearings are bad. Last thing left to check would be the
rear brakes. They were all new last Dec., before I got the truck. I
tried pulling a front caliper a couple weeks ago and couldn't get it
off, seemed like a metal clip was holding it someplace. I didn't have
that problem with a buddy's 2001 S-10. Both have dual-piston calipers
Truck in question is a 2000 S-10 ZR2. My tire pressures are a little
low (under 30 all around) but still equal, so that's the first order
of business, bumping them back to 30 rear, 32 front.
Mike, I think it's a pretty safe bet that your right front wheel
bearing is gone. We do tons of wheel bearings on the T trucks.
As another poster mentioned, the bearing can be noisy and not
have any discernible play.
What's the avg. mileage you see on the failed parts? I've got less
than 70,000 miles on mine. I realize the ZR2 will wear them out
faster with the bigger tires. I think I can tackle this on my own,
seems fairly straightforward...
I tried to pull the caliper today and couldn't get it off. I tried
taking the whole assembly off, bracket and all, but couldn't break the
bracket bolts loose either. Any trick to this? I pulled the calipers
off an '01 this past summer with no problems.
If you're pretty sure on the problem being the bearing, I'm gonna go
ahead and get one at some point to swap it out. Gonna try one last
time tomorrow to find the source, then I gotta get the front end apart
to replace it. Any tips for replacing the part? I'll be finding a
Timken or BCA bearing, can't shell out the $400+ for a dealer part...
The bolts that hold the bracket to the knuckle are extremely tight.
They have factory loctite on them, and I use a long bar to get them
Gotta run off to Edmonton, so I won't be around for a day or so.
Yes, no, maybe. I grew up in South Dakota, and have spent ample time in
North Dakota. Same goes for any point in either of those states. I've
contemplated going to Edmonton, but every time I pull out the maps, I find
myself going "my goodness that is a long way from anywhere." I hope to make
it to Banff sometime in the next few years, and might take in Edmonton on my
Well, if you do happen to get out to Banff, feel free to stop in
and visit. You will end up going thru Calgary to get there. Edmonton
is only a 2.5 hr drive from Calgary, so it's not much of a drive from
I haven't been out to Banff in years, and I only live an hour away
from it! That's usually the way it goes when you live that close to
a place like Banff. I don't know if you watch "The Amazing Race",
but the last episode had the travelers going from the Philippines (where
I grew up) to Banff and Calgary (where I live now). Good stuff.
I'll keep it in mind. I'd like to go to Winnepeg, then over your direction.
I've thought about it for honeymoon type trip, but first I have to get
married! (slowly working on that). We'll see. I will make it to Banff at
some point, I am committed to that for sure. How did you grow up in the
Philippines and end up in Calgary? Talk about stark contrasts!
My parents were missionaries over there. Once I finished high school
there, there wasn't much for me to do. Came back to Calgary ( a lot
of my parents financial support came from this city) and settled down
here. As far as city life goes in Canada, I don't know if you can
beat the life here in Calgary.
The big contrast for me has always been the weather. I "put up" with
this weather, but I'd prefer to live in the tropics any day of the week.
I had kinda guessed that might be the case, but didn't want to jump to that
conclusion. I have a couple of former (retired) missionaries from the
Philippiens in my church, and a friend here at Seminary who came from the
Interesting...here in Canada..the initial guess is usually...."military", or
"business"....but almost never "missionary". Probably an indictor of
one of the many differences in cultures between Canada and the USA.
Of course, the vast majority of missionaries in the Philippines were
Americans....so I basically grew up "American". I even knew and
recited the Pledge of Allegiance and saluted the American flag and
all that. At one point, we few Canadians attempted to have the
Canadian flag present in the classroom and have the Canadian
anthem sung....but none of my American classmates would have
anything to do with it. I suppose it smacked of being unpatriotic.
As far as I can tell, we Canadians are not very hung up on that
sort of thing. Personally, I do tend to keep an eye on America
politics....and I tend to be more conservative then most folks
that I know up here (with the exception of my wife..heh heh)
Well, I thought removing the bolts was gonna be the hard part of this
job. Boy was I wrong! Those bolts came out REAL easy, the hard part
was getting the hub outta the knuckle. I had to ask a neighbor, who
works on cars a lot, to come over with a BFH (5 lb sledge) and brass
drift to help me get it out. Took him 5 mins. to do what I spent 2
hours trying to do. It's all buttoned up, the hum is gone.
BTW, Ian, do you usually have to use a box-end wrench on the upper
caliper bracket bolts? There wasn't enough room to get a socket on
there . Maybe it's a thing with the ZR2 control arms, my buddy's
regular S-10 wasn't nearly as much trouble.
Yep, box end is all that will work. Plus, if I remember correctly,
the bolt won't come out unless you turn the steering all the way
to one side or the other (depending on the caliper you are working
