Unsworth Posted September 29, 2009 Share Posted September 29, 2009 Hi all.. I have my name on a Discovery rear axle (Wish to replace with mine as I want discs all round) It comes with new pads and is even painted ready to fit with all the lines for £50 (BARGAIN).. How easily is it to replace the axle with the one on my 90?.. I have had the rear springs and shocks off and one of the trailing arms so I know everything should un-bolt easily!.. My main concern are the brakes? (Apparently it is a case of turning the "T-piece" around on the disco axle to mate up with the existing pipe work?).. Also my other worry is the A-frame joint? I have use of axle stands, Trolley jacks, Hi-lift etc. Also is there anything I should do before I fit the axle?. Such as replacing seals or perhaps brake lines?.. I am going to fit a brand new A-frame joint whilst I am at it. Any advice appreciated!. Many thanks.. Matt Quote Link to comment Share on other sites More sharing options...
Mark Posted September 29, 2009 Share Posted September 29, 2009 What age is the discovery? The only issues that come to mind are that the 300 series discos have 3 bolt flanges on the diff rather than the 4 that you will need. Other than that it should bolt straight on. I couldn't comment on the brakes other than that if the Disco had ABS there will be 2 separate lines rather than a t-piece... hth Mark Quote Link to comment Share on other sites More sharing options...
88 inch of pure pleasure Posted September 29, 2009 Share Posted September 29, 2009 as mark said realy,its not a hard job in all fairness but be awair if your changing the a frame ball joint they can be a pig if the bolts are rusted in as i recently found out Quote Link to comment Share on other sites More sharing options...
disco tony Posted September 29, 2009 Share Posted September 29, 2009 If the diff flanges are different, conversion flanges are available on the bay of ee's or elsewhere. Do a forum search. Quote Link to comment Share on other sites More sharing options...
Unsworth Posted September 29, 2009 Author Share Posted September 29, 2009 If the diff flanges are different, conversion flanges are available on the bay of ee's or elsewhere. Do a forum search. I doubt it will be different.. The lad selling it promises it will fit straight on or I can have my money back.. He bought it to go on his mates but his mates lost interest in land rovers. But I prefer to get some second opinions. Can you describe what you mean by Diff flange?. Im guessing you mean the part which the prop shaft is bolted to using 4 x 9/16th bolts?. Thanks..

Retroanaconda Posted September 29, 2009 Share Posted September 29, 2009 Correct. On Defenders and earlier Discoverys it was four bolts, on the later Discoverys it was a three-bolt flange, different design. They can be swapped over anyhow, you can take the one of your current 90 rear axle. Quote Link to comment Share on other sites More sharing options...
task Posted September 30, 2009 Share Posted September 30, 2009 My 1998 Disco V8 has a 4 bolt flange on the rear axle. I'm guessing this was changed at some point previous to my ownership, which is a little strange as, other than an LPG conversion, it was 100% original before I got my hands on it.

Aragorn Posted September 30, 2009 Share Posted September 30, 2009 task: Does your V8 have the rotoflex coupling? edit: seems that the late V8's (Microcat says Chassis VA541628 on) didnt have this coupling, and just used the same prop as 200 series discos.

muddy Posted September 30, 2009 Share Posted September 30, 2009 I'd forgret about the use of the hi lift if i were you. Take the oppurtunity to examine the trailing arm mounts for corrosion around the welds and also check the diff pan. Depending on how much of a rebuild you want to do i would either completley strip down, repaint, new seals and bearings, new pistons etc etc or just whack it on. Paddocks do a 'rear bolt kit' for about £20 its worth buying. May aswell fit new brake lines while your at it and a new rear flexi that way you know its good. While you have the axle on the bench take the oppurtunity to use a hex/flank drive socket to undo the bleed nipples, bleed bolts and brake pipe unions on the calipers BEFORE you have to do it laid on your back/eating wheelarch with DOT4 running down your sleeve and skinning your knuckles on the springs.

Reiny Posted September 30, 2009 Share Posted September 30, 2009 I agree with Muddy. I bought a lovely pair of 50th anniversary axles a few months ago. They had only covered 30,000 miles and had been lying on a shelf since 2002. I stripped them down and replaced all seals and gaskets, regreased all bearings (they only had the thinnest of thin smears of grease) and rebuilt the calipers before fitting them. I would rather do these jobs on the bench than when the axle is fitted. Quote Link to comment Share on other sites More sharing options...
lrfarmer Posted September 30, 2009 Share Posted September 30, 2009 when i fitted my disco axle i put new brake lines and yes i think i had to turn the T round i fitted new discs and pads mine was a bit rusty so i did have to sort it and paint it.
