Title: Brake Discs
Post by: jay140285 on January 18, 2013, 09:06:23 PM
After Nat's mishap today,

The rear disc is in 2 halves, Do I need to replace both sides or just the damaged one?

Cheers

J

You always replace in pairs.

A hit that hard might have done more damage, fingers crossed I'm wrong

 :iagree: new discs and pads required, and you could have a buckled wheel now or bent shaft

Ok, so pair of disc's and pads.

Wheel still need to sort, I know Jedi's got a set but need the 3inch lift to fit them.

As Cockney Boy stated I am concerned about other damage,

What else could it have done / is there anyway to check shaft as Rob mentioned them?
Title: Re: Brake Discs
Post by: Panic mechanic! on January 18, 2013, 09:37:50 PM
you can always swap them over for the standard ones i have here to get you about if you want?
Title: Re: Brake Discs
Post by: jay140285 on January 18, 2013, 09:39:52 PM
Cheers Rob, will get disc's from motorfactors in the morning then wobble over if your about.

Title: Re: Brake Discs
Post by: jay140285 on January 18, 2013, 09:49:57 PM
Eehhh??

So jack all 4 wheels onto stands?

The wheel is fucked so its not going to show true and straight?

I am confused

Wooo! done that a few months ago! :banghead: :banghead: :banghead:

Kerb 10 Jeep 0

I wrote off the wheel, split the disc and bent the half shaft :010:

I eventually sourced a new shaft and fitted new discs!! pads and shoes!

Keep in mind that the Diesel half shaft is 1" shorter than the petrol ones ( no idea why but they are!! oh and there a larger diameter too! - more torque you see!  :icon_biggrin: :icon_biggrin:)

Good luck

if the shaft is bent, which is highly likely, it'll be cheaper to sling another s/h axle under it .
Title: Re: Brake Discs
Post by: jay140285 on January 19, 2013, 11:32:56 AM
Wheel and disc off, just taking wheel to see its its bent at rim of the face.
Title: Re: Brake Discs
Post by: Cockney Boy on January 19, 2013, 01:05:11 PM
i would get it jacked up and have a close look cockney had 2 bent shafts

I'd like to point out I think the shafts were already bent  :icon_sad:
Title: Re: Brake Discs
Post by: jay140285 on January 19, 2013, 02:04:28 PM
Wheel is usable, only the rim bent.

But Shaft is screwed!

Do I need specialist tools to replace the half shaft,

What do I need, obviously new shaft, do I need a fitting or bearing kit as well??
Title: Re: Brake Discs
Post by: Bubba on January 19, 2013, 02:28:41 PM
shaft if sh will come with a bearing and seal on it but i would replace with new anyways
Title: Re: Brake Discs
Post by: jay140285 on January 19, 2013, 02:30:22 PM
Is it a drive fix or specialist tools needed?
Title: Re: Brake Discs
Post by: Dutch on January 19, 2013, 02:39:58 PM
If the front is anything to go by, just spannering, hubs off and all that, pry oil seal out, and it will just pull out.

Oh btw, if anybody has the need for a petrol front offside WJ halfshaft, I've got one going for free. Came with the CV joint I bought in Belgium.
Bloody petrol ones are an inch longer (as somebody else already pointed out elsewhere)

Good luck,
Title: Re: Brake Discs
Post by: Bubba on January 19, 2013, 02:52:34 PM
if you do fit a new bearing on the shaft a press is by far the best tool for fitting
Title: Re: Brake Discs
Post by: jay140285 on January 19, 2013, 05:51:46 PM
Look like Jeep is going to Carlos next weekend and Me / Rob / Tank / Carlos are going to do an Axle swap.

Tank looking into borrowing a flat bed unless anyone local have a trailer we can borrow.

That does seem a lot of work for a bent shaft  :017:

I'm guessing the ratio's are definatley the same ?
Title: Re: Brake Discs
Post by: Cockney Boy on January 20, 2013, 06:58:43 AM
Changing the shaft over and axle is the best option Jay. Ask a certain Birty some cash and he can do that for you
Title: Re: Brake Discs
Post by: daggie on January 20, 2013, 08:10:48 AM
I can see the sense, axle off carlos 175 squidsish
drive shaft, bearing kit, discs, pads etc will be way more IMHO  :003:
DON'T forget the piss taking too  :hysterical:

Eaxctly this, except axle was a bit cheaper off him.

I got new disc's and pads yesterday so will swap them over but motorfactors did them at trade so saved a few ££.

As you have said its the cheapest option to get it mobile again.

Post by: MOCAJ on January 20, 2013, 03:44:09 PM
Q.  If a fuse blown would you re-wire half the house ???

fit the shaft and discs from the other axle, if you don't know the history you are taking a gamble
Title: Re: Brake Discs

thinks its more a weather related repair and having the tools to do the job.
Title: Re: Brake Discs
Post by: MOCAJ on January 20, 2013, 05:01:08 PM
i could swap a shaft in 1/2 hour using sockets and a pair of mole grips, on the roadside if it came to it. If you want to fit a new bearing and seal then a dremel and press make it nice but can be done with a long piece of pipe and a chisel. Swapping brakes is easy and if you clamp the pipe you will need little bleeding.

Replacing an axle is a big job, by all means buy the axle as it is cheap but dont fit it all. I dont understand the logic  :icon_rolleyes:

Indeed, it was bloody cold sorting the wheel out and changing disc's yesterday outside.

So what ever fix we do we will be warm!

Come on Mr Van Dyke keep up.

Must admit, I'm with Mocaj & Robsroti, buy the axle, keep what you dont need as spares. You know your diff is fine so leave it alone. No need to trailer the car either & fix can be done at a more relaxed pace nit fighting to get it done to get it home

Interesting thread, what would you suggest PanicMechanic :peekaboo:
Title: Re: Brake Discs
Post by: Shaggy on January 20, 2013, 08:05:11 PM
If your just using basic hand tools, swapping the shaft is far simpler & quicker, if your using air/battery tools swap the axle! Build the new brakes up on the floor, unbolt the prop, gun the top & bottom arms disconnect the brakes & arb & drop it down on a trolley jack! As good old mister haynes says reverse the procedure!
If the "new" axle is good I know which way I would go! Just as a matter of interest if it got smacked hard enough to smash the disc & bend a half shaft has it bent the control arms or tweaked the unibody mounts?
Title: Re: Brake Discs
Post by: Panic mechanic! on January 20, 2013, 08:09:10 PM
seeing the disc first hand i would , i would go for an axle swap  cos she may have damaged /cracked / tweaked the casing itself
Title: Re: Brake Discs
Post by: jay140285 on January 20, 2013, 08:11:12 PM
We will have power / air tools.

New axle is lower mileage than the current one and last service on my diff there were some metal filings in there.

From what I can see everything else is straight, but Carlos will have parts on hand should be need them.

Jay - I'm all for collecting spares for "next time", but I'd go with the shaft swap only!

As I said above I slid into a kerb in my Wj whilst towing a Land Rover on a trailer - so it was a decent smack!! :lol_hitting:

The shaft swap is relatively easy and a damn sight quicker - as for the Uniibody/ suspension arm damage - I checked mine and no issues :icon_super:
I reckon the suspension soaked up the sway - that's what the bushes are for!

Keep in mind that if you go for the axle swap - check the ratio's!

Good luck and the sooner your on the road the better
