Differential problems!!! Need help asap!!

[Franger99]

I bought a lrp.28 spec 3 about a month a ago and its destroying my car. It broke the rear diff., i bought all new gears and bearings. Broke it again, fixed it again.

I got the one in the rear and putted it in the front. It was all good for about 10 mins when it broke the two of them.

Is there any company that makes a really hard to brake differential. Because I'm not spending my money on something worthless.

Note: the gears i bought were bulletproof gears.

Are you shimming the diffs ?

 

[Mickey]

if you are running bp diffs in stock x bulks flex could be the issue

 

[xll-SavageX-llx]

I was going to say that next Mickey LOL
I'm still running my stock diffs, 4 gallons on the F4.1, 1 gallon on the ERCM 4.6HO

The flux is running stock diffs too..

So what am i suppose to do/buy. I'm new to this hobby can you please be more specific please.

 

[Mickey]

the flux bulkheads are composite so they are harder then the stock hpi plastic ones. I'm not sure on the part number. but you basically need the flux bulkheads

I had the same problem with my xl diffs,i also have lrp engine.Shimed stock diffs, still destroyed em.Replaced stock diffs with BP diffs and cahnged spider gears problem solved. If you keep the stockers it will keep happenin.Good luck!

I don't get it. My friend's xl doesnt brake them and the5.9 has a lot of torque

The 5.9 is a turd
Only thing it has is over heating problems.

Ok so if i get brand new diffs i have to change the case

Yeah the stock cases flex a bit causing the diffs to shred. You can get aluminum cases from GH but there a little pricey.

 

[Mickey]

yep get the flux bulkheads and you should be good

here a link to the case http://www.tcscrawlers.com/HPI-Composite-Gear-Box-Bulkhead-102272-p-17463.html

i never had a problem with stock diffs in stock cases running a modded picco, modded F.

but, if you don't shim the diff properly, the side-load on that crappy 10x16mm bearing can easily kill it really throwing off your alignment and causing failure.

now that i think of it, bank ran his modded picco and modded novarossi before the bullet-proof diffs or the flux bulks even came out.

& btw- ive also grenaded 2 10x16mm bearings on my flux in GH Alloy cases. caught it before it grenaded the diff, but I'm thinking more of a problem with that crappy bearing & shimming than the bulks.

Ok i just got 2 brand new xl diffs i hope they don't brake

Same here Fred, never had a problem with stock diffs nor cases.
Like you said as long as they are shimmed right your good.

 

[Franger99]

Ok so should i shim the new diffs when i get them?

 

[redneck]

yes you should

 

[Franger99]

Ok i shimmed the diffs (not the new ones) it went great for 20 mins then broke again. I think I'm going to wait for the xl diffs and put those on!
