CV Joint Repair question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

'72 Chevy Suburban · 03-19-2005, 06:56 PM

The U-Joint on the LF axle in my '77 K10 is shot, which explains why there has been a squeaking noise coming from that corner as I make a turn. It looks to be pretty tight in there and I am wondering if there is enough room for me to replace this U-Joint without doing some major disassembly. What is the best way to approach this? I hope to get the work done this weekend.

BTW, I verified that the U-Joint was shot by rotating the tire and watching the joint. There was obvious slop between the cap and the cross.

Thanks,

According to a friend of mine, the hub and axle needs to come out... I'll be doing this today (and will be monitoring the board as well) in case anyone has advice.

Thanks,

Hub, spindle, and axle need to come out. Don't screw up your spindle when you pull it.

Yep have to remove the hub and spindle to pull the axle out. Would be a good time to do the ball joints with it all apart.

Thanks, I'll have to check them out. Right now, I am at the point where the Spindle doesn't seem to want to come out. It's real temptiong to get out the BFH, but the FSM suggests using a dead blow.

Persistence and patience, I guess..

Hopefully I found the source of the clunking noise today... One of the
internal gears to the locking hub had some wiped out teeth. Since this
is fulltime 4WD, I am thinking that this might be the case. It
certainly gave me a good reason to buy a new set of WARN hubs when I
went to the parts store to get my spindle nut wrench. Here are some
pictures of the progress today.

Note the backing plate picture with the wasted slinger. Is there a way
that a replacement slinger can be purchased without having to replace
the whole backing plate? Not trying to sound cheap, but the backing
plate is a substantial chunk of steel and it is in great shape.
Probably not a cheap part to replace.
I will get the U-Joints pressed in tomorrow, hopefully. In the mean
time, I will press the '72 Burb into daily driver duty.

You may be able to buy a used backing plate fairly cheap; I threw 2 of them away several weeks ago. As far as spindle removal, a tapped hole would have been great. I have a spindle puller that works real good, I can have 'em out in about 2 seconds.

Hmmm.... A spindle puller! Sounds like something that I would have killed for yesterday! Does it thread onto the spindle itself and then have something like a body puller (slide hammer) attached to it? I was dreaming up a similar animal yesterday...

Yep, that's exactly what it is! It works great too.
