I just noticed a small puddle of gear lube on the driveway and upon
inspection found the right front axle shaft has popped out of the axle
tube by about 1/2 inch. I don't know ho far the truck was drive like
this but probably less than 50 to 100km. Questions:
What retains the axle in position (pressed on bearings)?
What is the likely damage (from those of you who have experience with this)?
What is involved in fixing this?
Tho' I'm not a Lic'd mechanic, I'm very experienced in Auto repair; just
haven't yet worked on these axles.
I've found the problem and ordered most of the required parts, except
the culprit; the axle retaining ring (snap ring) that retains the axle.
Apparently the failure of this $0.50 ($8.00 from GM) part is not
uncommon that is why GM has discontinued it's supply and insists that
you buy a new "retrofit" axle with a larger retaining ring and groove
for about $500. Since the previous one lasted 6 to 10 years, I just want
the retaining ring but GM won hear of it. Local drive line shops have
the sam problem. Has someone else come up with a solution? One person
has told me the old axle groove can be widened to accommodate the
retrofit retaining ring (which has a round cross section instead of the
traditional rectangular). Has anyone done this?
b.t.w. This is the same front end used in the K3500
A K2500 front axle isn't necessarily the same as a K3500, and it's really
just better to identify your axle. I would expect a 3/4 ton to have a D44
and a 1 ton to have a D60.
Check out www.ck5.com they are all about upgrading their axles and whatnot.
Really? I thought the IFS cluster fuck was later on. My bad, but he still
should refer to the axle by what it is, don't you agree? I mean he must know
to have bought parts for it...
So what you and bret are saying is this;
His 2500 could either have an 8.25 IFS, a 9.25" IFS, OR he **could** have a
D60 from a crew crab under there....
Only lamers like Doc keep stock axles under the truck......
No, what I'm saying is that if you read the original
post carefully, it would have been quite obvious that
the poster was describing what could only happen to
an IFS front diff. Of course, this assumes that you would
know enough about the differences between the solid axles
and the aluminium front diffs.
I repaired it. Seems fine now.(:/
I carefully measured the axle and remains of the broken retaining ring
and found some very close matches on a couple of online catalogues.
I ordered a couple of (imperial for a metric? axle) retaining rings
through a local bearing wholesaler for $2.80 each.
Here are the numbers if anyone cares:
GM dealer was not much help. They even gave me an obviously wrong axle
bearing even though I spent an hour at their parts counter and they kept
the old one for comparison. >:(
I replaced the right bottom ball joint (for the second time in 8 months
- crap part, and 3rd time in 3 years.) Yesterday I found the top is also
kaput (I know, I should have checked that sooner but I wouldn't have
had the time to change it at the same time as I was doing the other work
To clear up any confusion:
9.25" IFS (8600lbs 2500/3500)
As far as going solid axle, that would be my preference, but so would so
many other things that aren't part of this truck that it isn't worth the
time. To boot; everything electronic on this truck is a problem; and we
won't get into the a-PEALING silver paint!
Many thanks to B&B Bearing and Mainland Transmission, Surrey, BC and
