    Default Drop arm removal tool

    Howzit guys,

    I'm busy with some maintenance and so far I've replaced all the steering ball joints and also tackled the drop arm ball joint - fiddly job doing it still attached.
    There's a sweat on the output shaft seal on the steering box so I'd like to remove the drop arm and replace the seal.

    From what I've seen online this is the tool I need to remove the arm with, but I cannot find it in any shop. Does anyone know where I can buy one. or rent one?

    be advised that applying brake fluid a day or so ahead of time helps to remove rust and other contaminants that binds it to the output shaft. we press it off with a hydraulic ram. sometimes a 20 ton portapack can't get it loose.
    we then resort to putting it under pressure and while under pressure, heating the knuckle with a acetylene torch. it normally then comes loose
    this can only be done with the box out of the vehicle.

    sometimes it is possible to weld a pipe onto the arm (one that will fit snugly over the output shaft) and to use a sliding hammer. the heat of the welding often breaks the "seal"
    try not to transfer any heat to the shaft - only the neck of the arm

    Thanks Landyluvver, I did not know brake fluid helps! Will let it soak in for a day or two, depending on how long it takes to get hold of the removal tool.
    My plan was to use a handheld blow torch to slowly apply heat and see if I can get the arm to budge off the output shaft.
    I had good luck this weekend using heat to get the balljoint threads loose

    if you bring a blowtorch near it in place, you will fry the seals!
    need to remove box and turn upside down
    then either weld on the arm to get the heat in localised area (not the shaft) or use a cutting torch.
    do not use a torch that will heat up the general area!

    i have on occasion resorted to cutting the arm off the shaft with a baby grinder but that only as an absolute last resort!

    Bugger, looks like I may need to pull the whole box out. I'll still try with the box in and see if I get lucky.

    Does anyone know where I could get hold of the puller?
    Will a normal ballpoint separator work?

    May sound abit brutal but the only way I managed to get mine off was to use a grinder and cutting disk .

    i tried soaking n all the other trick even broke a puller ...

    Where did you get the puller? I hope I get lucky and mine comes off without too much fuss, else I'll start looking at these alternative methods

    Ja, don't take the above mentioned lightly. I recently dismantled a box. 20 ton press did nothing.
    It only scared me.
    I didn't want to cut. Later I used a heavy duty puller and acetylene torch.
    While heating apply pressure after 2 tries it popped. But seals where toast.

    Just take note that seal replacement on this box isn't always successful.
    Seal quality and fitment is very important.

    if you can't get the tool maybe get measurements off drop arm where tool needs to hold onto and then get a laser cutting place to cut out the tool, you then just need to get it threaded and tapped, and then you have a tool

    I tried removing the drop arm on my Jeep steering box. Soaked it for a week with tension on the puller. It did not move. I am sure. If i come close to that thing with a torch, the seals will be toast. I am still contemplating whether to continue with the disassembly or not

    While it has tension with a puller, give it some proper bashes with a 4 pound around the sides of the arm (not on the nut or the sector! But keep the nut on to avoid it flying off). Don't waste time with something small and ideally use a steel or brass hammer, not a cast cheapy.

    I have been able to get arms off this way, even on my 70 year old stuff.

    I am a qualified old school fitter. Done all of the above, and tried to stretch it with 4pd and 2pd hammer on each side. Welding on the outside might get it loose but, the shrinkage when cooling down has me worried. I have a 10 ton puller which i might try next.

    Ok. Sorry if I offended. I hear you on the heat issue, hence why I stay away from the blue wrench.

    Just thinking, have you tried using an impact wrench (as in air/cordless) on the puller? The hammer action should help breaking the joint but the puller will take shots.

    I see Microtec the tool company makes a drop arm puller for <R300, I'll try find one tomorrow and see how it goes.
    As for the seal replacement, I've read its hit and miss but worth a shot for the price of a seal kit vs. a new or recon box.

    If I don't come right with these repairs where can I get a recon box?

    This method worked for me...

    Now the hard bit - the drop arm has to come off the shaft, and usually a big puller is needed to do this. There are two
    lugs on the drop arm, and I have a long chrome vanadium bar with a tapered end on it. From inside the engine bay the
    rod reaches down to the top of the drop arm on the lugs, and then I belt it hard on alternate sides until the arm lets go.
    There's no other way to remove the arm apart from these two methods, using heat will damage the steering box seals,
    but if you are going to replace the whole arm then you can cut best of the way through it and then crack it with a chisel.
    Anyway - after about 10 minutes, the arm comes loose. With the rubber boot removed, the corrosion can easily be seen.
    Remove the circlip and the guts of the joint will come out with the exception of the top ball seat.

    Just beware that there are 2 needle roller bearings above the bottom seal of the sector shaft.

    Banging might damage them.

    Waiting for a quote for a puller (I think around R350) and seeing I can get a new drop arm for R450, seems as if it's going to be less effort to cut the arm off and replace with a new one.

    Would it be best to remove the box to replace the input & output shaft seals, or would I manage fine with the box still bolted onto the chassis?

    Update: after fighting the drop arm for an entire day I removed the steering box and got it sorted.

    I need some clarification on instructions after refitting the steering box. Please can someone offer advice on the below process?

    - Loosely bolt the securing tie bar onto the steering box
    - centre the tie rod end mount (I think) in the hole and bolt down to 81NM
    - torque the tie bar nuts to 81NM, then back 1 turn

    test drive vehicle.
    - torque tie rod end mount to 110NM
    - then torque securing tie bar bolts to 81NM

    Is this the correct procedure and are the torque values correct?


    I'm following the process outlined on Land Rover Toolbox's youtube video. The images are screenshots off the video.
    I did search through the online manuals and did not find the info I was looking for.
