diff / shaft / speed sensor question
ditchlewis - 4/10/07 at 09:50 AM

Ive tried the speed sensor halfway up the prop.... broke the sensor

ive tried the senson on the diff reading the bolts ....... BROKE THE SENSOR

the diff i have has push in shafts and the diff is firmly bolted to the chassis. do the shafts move in our out as the suspension goes up of down??? is this a safe place to mount the sensor?

at 40 quid a throw i'm running out of cash for the sensors.

I have mounted mine on the inner driveshaft joint, and the sensor on a little bracket bolted to the Torks bolt on the adjuster ring locking thing on the side of the diff, if that makes sense. Works a treat and you can get at it easier.

The only problem with taking a reading off anywhere near the driveshaft is they'll move up and down as the suspension moves. Not a whole load but the hall effect sensors are effected by distance IE you'll get an unrealiable reading. If you put the sensor too far down it'll get walloped everytime the suspension moves...
when you're using push-in shafts (so you can't use a trigger wheel on the Lobro bolts like I did) the prop is the best place to use... Unless the diff and the engine are moving around enough to move the prop, it shouldn't hit the speedo sensor...

Does your diff have a cradle to attach it (via rubber mounts) to the chassis? If so and you have welding access you could attach a sensor mount to the diff cradle- then the sensor would move at the same time as the prop / diff.

The inner CV joint does not go up and down thats where mine are and it works.

i was using a hall effect sensor...

the prop moves a bit may be the gear box mount is not up to it.

but the bolts one the diff should not have moved though unless the diff is worn.

so i think the consensus is that the sensor should be mounted on the front of the diff and read the bolts on the prop.

need to check the diff for movement.
