    Installing new front differential bushing

    My front bushing blew out like everyone else's many moons ago. I finaly got
    tired of the clunk and bought a new GM front bushing part# 19121910
    I have the perfect tool to install the new one ( it sucked getting the old one
    out). My question is do I need to heat the case boss for the bushing to go in. I read Lindsays post about using the Ball Joint installer, thanks!
    I Just dont want to bust the case.

    Re: Installing new front differential bushing

    Just pick an old socket or piece of pipe, something you can beat on.
    Make sure it matches the size of the outer shell on the bushing. Support the diff and just drive it in.
    I used a socket, now it has a hard time accepting the impact gun but oh well.

    Actually Kent Moore makes a tool that will remove and install the bushing in less than 10 minutes.
    I don't even have to take the diffs out of the car anymore. (you do have to lower them down and take half the suspension apart to get to the bushing though)

    I am confident that it wouldn't be worth the price of buying the tool to do one bushing.
    I have another one to do on Monday.
    (if I can get to it)

    Just keep it square and drive it in, remember hit the outer shell, not the center piece.

    Re: Installing new front differential bushing

    What all do you have to take apart on the suspension? The way I was thinking about doing mine was to remove the three bolts holding it to the rear cradle, lowering it down and then R&R the bushing.

    Re: Installing new front differential bushing

    yep, just the 3 bolts and the prop shaft bolts is all you need then just yank the front down past the exaust
    pipes. Have a rag handy to wipe up the fu**ing gear oil that is going to run out past the FU**ED up pinion
    seal. I just cant believe this day and age its so hard to design a seal.

    BTW, is there a recall on the pinion seal? My diff (replaced in 05) was a 1/2 quart low. Had it filled about a year ago.

    I take the right axle out, the tool requires removal of the axle.
    Removing the axle makes it easier to knock out or pull out with the tool.
    Of course I have a lift, a transmission jack, and lots of other tools at my disposal.

    Re: Installing new front differential bushing

    If u have a new rear put in does this bushing come with the new rear or is the old one used? I had a new rear put in about a month ago but it still clunks big time..

    Re: Installing new front differential bushing

    Thanks for the link on the recall! This was a new bushing in a 05 diff. CLUNK IS GONE!!!
    I see the recall is from 05 and newer, well my car is a 04 with a 05 diff how should I go about getting
    a new seal? I'll post on the recall thread as well.

    The pictures that my parts guy shows me a new rear has the front bushing. But I wonder if the rear two bushings might have something to do with excessive clunk.

    Re: Installing new front differential bushing

    OK I just got some excellent feedback about installing the front bushing.
    If you are going to have yours replaced, insist on have the tech "Clock the
    bushing so its in compression not in tension". If the sevice dept doesn't
    know what your talking about drive your clunking V to another dealer.
    When I put mine in today it was a total no-brainer which way the bushing
    should be "clocked".

    I now understand why some people get clunk after replacing the bushing. It wont last at all if its installed in tension.

    Re: Installing new front differential bushing

    To lower the axle the way we do it in the shop you remove the right axle. To remove the right axle you basically have to remove the right rear knuckle.
    There are several nuts and bolts that hold it in place, they are almost all unique so keep track of them when you take them off.
    The big nut has to come off the axle as well. GM recommends replacement if you take that nut off but it isn't critical.
    Be careful on the right output seal in the diff when you remove the axle, don't cut it or tear it.
    The brake caliper will also have to come off, 18mm bolts and they are in there nice and tight.
    Apply red loctite to the bolt threads before putting them in and torque them to 88 lb. ft. when you reassemble.

    I think I answered in the other thread about "how to get a seal replaced".
    You buy one and put it in or have it done. The recall covers a certain parts run from the manufacturer. Any seals outside that run are not subject to the recall. There is no real thing saying that because a bunch of them are bad that they are all bad, sometimes it can be true but...
    Your dealer might have pity on you and goodwill it depending on how many miles you have.
    If they wouldn't fix the bushing, I doubt they will fix the seal.

    You are right, it has to be installed correctly or it won't work right, I have seen some that were not installed properly. Pretty sad really.


    Oh and if the diff is replaced it comes with a new bushing installed in it.
    The only thing you have to install is a new vent, hopefully they did that.
    If there is a clunk they should recheck their work.
