Spearos Posted March 18, 2012 Share Posted March 18, 2012 Just a quickie, tomorrow I plan to replace the A frame bushes. While I'm at it, it seems the perfect time to give the arms/mountings a good clean and paint so rather than doing one arm at a time (leaving one arm attached to prevent movement) I am thinking about taking the both arms off at the same time. I plan to leave the balljoint and fulcrum attached to the axle and to remove both arms, so is it just a question of supporting the chassis with the road wheels resting on the floor - to prevent things moving whilst the arms are off? Any suggestions as to the easiest way to do this would be received most gratefully! Quote Link to comment Share on other sites More sharing options...
potato head Posted March 18, 2012 Share Posted March 18, 2012 I did this last week but changed the ball joint and left the arms attached to the chassis. I jacked up the axle and put stands under for support. This keeps the axle in the correct position for me to do the ball joint. Quote Link to comment Share on other sites More sharing options...
gruntus Posted March 18, 2012 Share Posted March 18, 2012 mmm, correct me if I am wrong...... Your trailing arms keep the axle locked in the correct position so the axle wont travel forward or back and your springs will keep the chassis at the same height. As long as you dont move the vehicle nothing should go out of place. HTH G Quote Link to comment Share on other sites More sharing options...
potato head Posted March 18, 2012 Share Posted March 18, 2012 But it can twist around the axis of the axle. The trailing arms, via the bushes, can allow the axle to rotate around the half shaft. Not a lot but enough to have a miss alignment (I found this out the hard way) Quote Link to comment Share on other sites More sharing options...
ukspike Posted March 18, 2012 Share Posted March 18, 2012 I did similar a few weeks back, but I removed the A Frame completely and the ball joint, I just had the truck up on a ramp, did not lift axle, it moved very slightly but nothing to much that a short bar under the tyre couldn't alter to facilitate the refit.

Disco-Ron Posted March 18, 2012 Share Posted March 18, 2012 YOU MUST SUPPORT THE VEHICLE ON THE CHASSIS!!!!!!!!!! Sorry for the caps, but this is safety critical........... the axle can easily twist itself and cause issues.....!!!!!! Quote Link to comment Share on other sites More sharing options...
Spearos Posted March 18, 2012 Author Share Posted March 18, 2012 As I thought Ron, but is it a requirement to have the wheels free of the ground? I guess not? - I thought maybe I'll just chock the rear wheels front and back to be sure. Quote Link to comment Share on other sites More sharing options...
Disco-Ron Posted March 18, 2012 Share Posted March 18, 2012 Thats right, you don;t need to have the wheels off the ground, in fact that would make it more awkward..... chock the wheels as you thought and support the vehicle on the chassis and you'll be fine, you'll be able to move the axle slightly to get the arms re-aligned when you come to refit them...!

Spearos Posted March 22, 2012 Author Share Posted March 22, 2012 I'd just like to report back a happy story - completed this Monday/Tuesday and wow! What a difference! It's transformed the 90, it's got to be the one single job I've done on the landy with the biggest improvement. Shunt when slowing in gear has been reduced drastically, bumps/potholes 'feel' less harsh and the steering feels a lot more precise, it's surprising how quick I can go around roundabouts etc now! Bushes came out ok using the drill-hacksaw-chisel method - I don't know what all the fuss is about! One thing to note is that I did the panhard rod bushes recently, the old items were the poly type bush and the inside mating face of the panhard rod had a lot of corrosion that needed cleaning up, compared to the inside mating faces of the A frame arms which had the 'normal' rubber type bushes. Another reason not to go down the polybush route perhaps? Quote Link to comment Share on other sites More sharing options...
Sirocco Posted March 22, 2012 Share Posted March 22, 2012 thanks for reporting back, doing this next weekend G Quote Link to comment Share on other sites More sharing options...
Spearos Posted March 22, 2012 Author Share Posted March 22, 2012 thanks for reporting back, doing this next weekend G Make sure you have a 1 1/16" socket & spanner! Or at least that's what I used for the 3/4" bolts that connect the arms to the chassis... Quote Link to comment Share on other sites More sharing options...
