Huge slack in the drive train

dorset.g · Jan 26, 2009

Hi All

Stuck in Cyprus my89 90 has huge slack in the drive train, in clonks as I take up the clutch and clonks again on acceleration and kind of wobbles about when the thottle pedal is eased, it's horrible to drive whats going on???
I have checked A frame bushes which seem fine, front prop is new rear seems stable, could it be gearbox, Half shafts or rear diff, how do I check these to confirm or otherwise.
Any help would be greatly apprecitated.

UJs ?

get a pry bar in between the yokes - unless they are well shot just pulling the shafts by hand won't prove anything

Hi sean

Done the pry bar thing they are solid mate.

try taking one of the props off - it might be unbalanced

have a look at the drive members/flanges for wear

Chock the wheels , let the handrake off and put her in nutral on the transfer box and rotate the handbreak drum back and forth and see how far she rotates , also pull off your hubcaps so you can see the ends of the halfshafts and splines for ware .
Do the same on the front . ( but rotate the front prop ) .
If nothing obviouse .
jack up one side front and back ( same time ) , put the transfer box into gear , and 1st gear then rotate the wheels and see what you got .

Try that for now

Hi All

Done all that has been suggested and been able to Identify the the root cause, it's not good news, Mainshaft/ input gear has excessive wear, as does the front diff, the rear also has some wear but not excessive, so I have three problems to solve, before I attempt to drive back to UK.
Any ideas any one? I could get new input gear and mainshaft sent out, but what about the Differentials what can I do with them? can they be repaired.
Any Ideas would be welcome.

If your mainshaft is badly warn it might be cheaper to throw in a good 2nd hand box then fork out for a new mainshaft + extras and labour times ( unless you got all the tools/press's and knowhow etc to do it yourself ).
your diffs could be adjusted by taking out the backlash on the pinion and crown wheel .
The rears easyer to do than the front ( have to strip down front hubs to remove the halfshafts / rear you take off the end caps of your hubs .

as a last resort get you home you can take off the front prop and engage difflock so you can still drive ( rear drive only ) .
Ive got the workshop manuals in PDF if you need them ( pm me with your email . )
