rear wheels locking underpower

[craigsimon]

Hi All,

Bit difficult to diagnose with words but I would appreciate some help. Today while taking off from the lights up a slight slope the rear wheels started locking (skidding and hopping) only when accelerating, in all gears, it appears not to be speed dependent but I was unable to get above 30km/h. Pulled over to check. no visible damage. half shafts appear fine. It only happens in forward. I was able to drive in reverse with no locking. I was able to coast forwards with clutch in, no locking. I was able to coast forwards clutch out, in neutral no locking (didn't try in gear with no power but gearbox is not making any abnormal noises). It is a clutch pack LSD diff. My guess is one of the pins that holds the spider gears/clutch pack has broken and is centrifuging out of place under accel and locking against the casing. Any other suggestions would be appreciated? before I pull the diff for a look on Sunday.

the only thing I can think taht would be is the diff.. crack it open and the problem will probably become obvious

[craigsimon]

thanks Draven, that was my suspicion. I'm guesing there will be a bit of a mess in there when I do get the cover off.

Thanks all I don't mind my misfortune being laughed at, I wish I broke it in a more exciting situtation than taking off at lights. I knew I broke something and I just wanted to confirm that everyone thought it was the diff before I pulled it out. Any way I got it out last night and am cracking it open later today. Q for SIKTOY did your cracked crown wheel damage the input pinion gear?

Even if the pinion gear looks ok you will need to replace it. If not there is a good chance it will be noisy and wear out really quick. The pinion and crownwheel are a matched pair and should be kept together.

[Sagluren]

you will find that the pinion and crown wheel, will both have an id number, these should not be interchanged as stated above.

yes yes, crown wheel and pinioin shaft are a matched pair.
