Broken Drivetrain?

[DearmanKE]

maybe someone can help diagnose my problems sad.gif

 

go to take off in first gear, normal driveing,

slowly release clutch with minimal revs.

clutch out, press foot down am average amount on throttle,

engine free revs then "clunk" and the car goes. keeps free revving and clunking over and over on short periods of time a couple times then drives normal until gear change, or change in throttle amount(like deceleration"clunks again") in which the same thing happens

 

clunk seams to come from rear end of car, but guess it could be anything

 

the car is a ke70 with a 4k, 4 speed, standard diff with welded centre(was welded when car was bought so not sure of quality of welds)

 

can anyone help?

Mate the first thing to do is drain oil from diff,check for metal

( sure you will find some :) )If not there try gearbox

drain plug , there will be metal in one of theses

could be you've stripped a few teeth off your crownwheel, and so the pinion slips and free revs the motor.

 

bad luck...

[TE278U]

or you've lost all the oil in the diff, the pinion bearing has collapsed, and your pinion and crownwheel are engaging then disengaging repeatedly.

 

that happened to me too.

 

don't drive the car anymore like this.

 

my diff locked up at 100 kph on the freeway, and put me backwards onto the side of the road across two lanes.

 

lucky not to hit anything....

took it for a hardish drive around the bloc in the wet

 

was one wheelering everywhere

 

then some bad crunches

 

n now the diff is gone completly

 

luckily on my street lol

turn the drum around backwards on the axle put 2 wheels nuts on a few turns and use it as a slide hammer.

also try hitting it in, sometimes they need to move that little bit inwards and they bounce back out, shouldnt matter since the difff is shagged haha

 

if not do what furryfrog said with a sledge hammer

[DearmanKE]

all done got axles and old centre out

 

new centre in

 

all good

 

everynow n then makes a few little clunk noises,

 

don't feel them just hear them

 

may have left some chunks of metal in the diff,

 

will probs do an oil change soon and check
