How tough to remove driveshaft?

12 posts in this topic

I need new u-joints on the rear driveshaft on my 03 Chev Suburban. I can save a few bucks if I take the drive shaft off and bring it in, instead of bring my truck in and having them do it.

Looks easy from search on internet - anyone have any opinion on this job? Seems to me the most difficult part is getting the truck high enough off the ground so I can easily access the four bolts where it bolts on to the transfer case. I don't have a lift.

There are four bolts that hold it to the yoke on the rear end. The other end has splines and slips off from the shaft in the transfer case. Make sure the wheels are chalked and the truck is in neutral. As long as you can get under the truck near where it bolts to the rear end you won't necessarily need to be on jacks. Have a drain pan under the transfer case just in case any fluid spills out of it when you pull the shaft.The rear joint will probably be a little stuck in the yoke so don't be afraid to get on it with a pry bar.

Make sure to mark the yokes, so you can install them in same position as they were before, this might eliminate eventual unbalancing.

If the driveshaft is 2 pieces, be sure to mark an outline on the center bearing mounting position on frame, so it won't be out of line.

Um, if your replacing them there is no way to put them back in the same position? whistle

Uhm, all the yokes are part of driveshaft(s), u-joints fit inside them. As might as well keep same position to avoid unbalancing. whistle

Valv, we kind of miss you around here!

I guess I still don't understand why its important to mark them but it may be an "old school" thing grin. I have never marked anything before removing or replacing and have never had an issue?

In Valvs defense, that is what were were taught in the "old school". Keep the yokes aligned as they were before removal just in case!

    • Switched up my pick at the last second in bucket A and put Wheeler in there. Great ledge fisherman and sounds like this dude puts in more time on the water then any other angler out there.   A. Wheeler B. Evers C. Tharp D. Herren E. Omori   Sounds like the bite has been super tough. Will be interesting to see how it goes. 
    • They are drumming like crazy now. In fact, I even hear them at night. My wife said when she was a teenager growing up in rural Wisconsin, she always thought that drumming sound was the nearby powerstation.    
    • Lilac blooms are here, just haven't opened. Hearing some reports of good finds in the Houston and Lewiston areas of MN. I checked some new public areas today on the MN side. Could be decent later but too cold and wet right now. Will check some early season spots tomorrow but won't hope for much with the cold weather.
    • Nice!  Must have seemed forever waiting.
    • 6 months later and he is home
    • Three favorites at the moment.  By the time they upload, I may change my mind.
    • A few from Maplewood State Park on April 16th.  Non-professional, but they stood still long enough for me to get 'em.
    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...
