Dual brakes installed, loud clicking of heavy braking?

[zaaaguy1]

I installed these brakes and man they are strong. I can lock them up on pavement with big joes on!!! The only problem is, during this heavy braking it makes a loud clicking noise like gears slipping or somthing. I can't isolate it though. I think it may be coming from the front differential. Am I causing damage, what can I do???

Well, its not normal. Thats a certainty! But as for where?!?

Any one of your driveshafts, any meshed gears and possibly hubs ripping apart rims. So many choices....

I would suggest, that with 3 wheels on the ground, and holding the spur, spin the one wheel up in the air. You may have to crank on it to recreate the slippage, and well, if its on a gear you might be hung up on 4 or 5 good teeth. Know what I mean?

It could definately be in your tranny too. So dont rule it out. One time I openned up a TMaxx tranny and found what looked like a rice frenzy. Thats what all the shards looked like splatterred all around hehehe And I heard the clicking for certain that day.


Just start poking it apart

yep it is the 1 thing that every one dose when they put duel brakes on (me also)

u have set them to sharp. ur brakes should NOT lock ur wheel up they should slow ur truck down to a fadeing stop

so yes ur front diff is shot
when u repair it do the spider mod


u beat me:juggle: :hi:

Thanks, I will check out the truck using the 3 wheel method and if it is the front diffs, I will put in the spyder Mod.

sry to hear, but with all the upgrades you did and threw in the picco .26, you should have did the spider mod gear first :nono:

I had that with the savage xl, I think it's the brake itself. It is starting to slip then brake, slip then brake making that clicking noise.

almost positive one of the diffs is slipping. good brakes are hard on the front diff. and savages are known for there weak diffs.

Could it be the breakrod that cranck over - moves to far. Try to check EPA while breaking.

With the engine off, apply the brakes fully, then lift the rear of the truck and gently push it forward. If it's your diff, it should slip/pop when you do this. If it doesn't pop/slip, then lift the front end and drag the rear wheels while pressing down on the cab to keep tire grip.

I actually had a bearing blow in my rear diff a couple weeks ago in my savage. They use too small of bearing on the outdrives which tend to crap out fairly quickly. At least mine did. Kind of bumbed me out at the time. I had just spent the money on alloy diff cases (the box the entire diff goes in) to help make solid gear mesh, XL diffs and 50K oil to help avoid diff issues for the season. Also installed brand new bearings from the XL diffs I got off ebay. I don't have more than 2 gallons on the diffs and I heard the dreaded popping when on the gas.

Kind of made my stomach sink considering the cost of everything I did to avoid this. Was affraid I'd have to pull the LRP and put back in my weak little 24.7 just to get decent drivetrain life out of it.

Turns out though, the out drive bearing disintegrated on one side. Even after all the popping, the XL pinion/ring gear still looked really good. I was mad at the time when it started popping, so I drove it anyway in anger... lol. I replaced all bearings with FastEddie bearings, cleaned all the gears up and put in new grease. Seems just fine now. I guess I'll just have to keep a close eye on those bearings.

Sorry for rambling... Just trying to let you know that XL diff's seem to be built out of some good stuff. So when you buy new ones, get them off ebay from an X or XL. I believe they run the same milled gears vs ones that look cast like the old savages.

I would say that your differential needs to be shimmed....With the extra braking capabilities combined to the big joes it might be too grabby for the diffs to stay engaged if theres too much slack..Good Luck finding the problem..
