Thread: THINK I BOUGHT A LEMON!!!

As you get drive with the CDL engaged I suspect one of your diffs or axles has given up the ghost. If an axles or diff goes all your drive goes to the least resistance and spines the brocken bits. Locking the CDL forces drive to the other end.

youve done an axle, drive flange, cv shaft or a diff center. (theres a slight chance you may have damage to the center diff)

Ive got a stack of driveline parts in a wreck Im about due to play swapsies with between my vehicles.

If theres anything I've got that will be in the leftovers/spares bin when I'm finished its yours for the asking.

IF theres a miracle and you can get your vehicle down to here when its happening (likely to be next weekend) or I can shove some other obligations out of the calander I'll see about trying to get them to you

As per Landover, drive flange has stripped.
This would give those results.
To check I imagine you could,
-engage CDL
-apply handbrake
-select PARK
-chock atleast two wheels, 1 front, 1 rear
-jack 1 wheel up at a time and try and turn by hand.

If you've got a stripped drive flange the wheel will turn.
Fairly easy and low cost repair.

You could narrow it down, with the engine running, foot on brake, get someone to look under the car at the tailshafts, as you put the gearbox into Drive with CDL disengaged.
Which ever tailshaft is turning, the problem is at that end.

Thanks heaps (everybody) for the quick advice & offers of help, the clunking/grinding noise came from the drivers side front (95% sure) as it could be heard on drivers side & not passengers but only on full turn.
I'll try jboot51's idea tomorrow if it's not raining to see what happens.

ps again thanks for your offer, very very much appreciated

most likely youve done the short half shaft on that side, very common <2hrs to fix if all the parts are on hand.


Short method.

jack up and jack stand front axle

remove wheel
remove rubber cup
remove circlip save the spacing shims
remove caliper, tie to spring
remove split pin, remove tie rod nut, remove tie rod
remove swivel seal
remove upper swivel pin
remove outer swivel housing+stub axle assembly
extract CV+axle. for axle removal If you're lucky its snapped at the CV end
remove the broken section from the CV (if you're lucky its snapped at the diff end) (no you cant have it both ways, they never snap in the middle or in a convenient spot that will give you enough to work with from both sides)
If its left a bit in the diff housing
Remove the fill plug, remove the drain plug + drain the oil
bend a piece of 6mm steel rod into a curve (adjust it as you go)
rotate the diff till you can see the side gear, insert the rod and hit it with a hammer to push the snapped bit out.
Extract the snapped bit of axle (I use a magnetic extractor or my mechanics claw, sometimes a bit of hooked wire will work)

do most of the above in reverse to get it all back together.

easy.

Mowed the lawn today, driest it's been, so I could work around & under Disco. Put it into ordinary drive reverse & moved it, no worries, mowed where it was then went to put it into D & guess what, no go. No noise or anything, so put it into CDL to put it back were it was, no worries, but I noticed there is a definite "lurch", my foot was on the brake as it should be. The back seems to go down or "bite" for want of a better term & it seems as if the front rises.
Now it's bloody well raining again grrr so will have to leave the above tests till tomorrow

Hi, I tried your 1st lot of suggestions - CDL engaged, in Park, wheels chocked, jack up 1 side at a time & turn tyres by hand.
Well.............they both turned quite easily, I got wife to spin wheels while I got down amongst the green ants (hate them) & watched the front drive shaft. It didn't turn & I couldn't turn it by hand, not even a tiny bit.
Does this mean diff is gone??
Thanks again for all the help

When turned are they turning in opposite directions or same directions?

With CDL in and back end on ground the front shaft should be still as it's effectively one shaft right through front to back
