Binding issues

[trap121]

Does anyone's rear diff make a weird clicking noise when you spin the wheels?

My esc keeps jumping up to 160-170 after 10 minutes on the track. I have dropped pinions and raised pinions and it is still the same result...hot esc, cool motor. I rebuilt the read diff and I still have the noise.

I think something back there is binding and causing the esc to overheat. I cant figure out what it is.

Any suggestions??

[bigred5765]

why are you running for 10mins??? any esc will heat up to that level after 10mins of running.

[jaans]

why are you running for 10mins???

How many minutes would you say it is safe to run then? 10 minutes sounds normal to me.

Do the diffs feel like they are binding? Also,when I first built mine I put a bit too much thread lock on the screws when putting the drive-shafts together. This made them sticky and clicky. Remove the diffs and the drive-shafts and check that they are free moving!

mine is a free as owt, just has a noise which is understandable dut to alloy chassis transmitting down it

[trap121]

They do feel like they are binding, when I twist it will spin, click then spin freely, then slow down and click again. There is no noise coming from the front.

The rear wheels dont spin together when it is lifted off the ground either. If I life the suspension arm they will though. I cant raise the droop in that arw as I only received one droop screw

This is what happens when I spin the wheels.....http://www.youtube.com/watch?v=-FWsfH4zT3M

That noise cant be normal

[mark christopher]

ur going to has to strip the rear diff/drive shafts and check em

[Jedi Master]

Thats not normal; strip and check your diff!

It is if something broken sadly, just a case of find out what has gone wrong and replace the part.

Let us know what is was though.

Take off the camber links and check the wheel bearings spin free

[AndrewCaunt]

Ashleys durango was clicking on front wheels. I found it was when you tighten wheels up to much.

[telboy]

Does it do it when its running? Have you tried it with the wishbones level? It could just be the driveshafts locating it the drive cups thats doing that when the suspension is at full travel.

[trap121]

Yes it does it when the wishbones are level. Im on my way home so I will check out the bearings and wheel nuts along with the whole diff if needed.

I'm pretty sure this it what is causing my esc to get so hot. In tried 17t-21t pinions and my esc kept coming off at 160-170, motor 120ish.

seems to be on the crown wmeel as it seems to click when the diff ids turning the spur

[trap121]

The rear drive shaft is not connected to the spur. It worked itself loose before the race yesterday. Tried to fix it and of course the set screw stripped. So I couldn't race

The bearings spin freely and it still clicks with the wheel nuts off. Time to break everything down

[kjuliussen]

Open the diff. im guessing that one of the large diff gear (part 310001) is split in half. I heard of one guy here that got his split in 3.

[trap121]

Took the diff apart and everything looked fine???? So I started to take the gear(310001) off of the outdrive and it snapped right in half

It flew up and hit me in the lip. Hit me so hard it drew blood. Not sure which way to go now

[kjuliussen]

I guess this happen because the gear is such a tight fit. next time i open my diffs, im going to sand down the hole in the gear so just slide fine.

[trap121]

Thats a good idea, I may do that myself.
