Calling HPI about metal bulkheads (did someone say Evo 5). They tell me that HPI isnt going that route for the Pro 4. I then asked if the bulkheads from the Cyclone will fit, considering the cars are pretty much identical. He tells me no one tried it and that the Hot Bodies people work differently than the HPI people. I then go to the HPI website and not only is the Pro 4 discontinued, but the Hara is listed as discontinued as well. They are shitting on us Pro 4 owners and it's a damned shame! I'm pissed as phuck right now!

Thanks!

I seem to be having issues with my front differential. It clicks a bit on initial acceleration and on corners. I've rebuilt it a coupe of times and it's good for about half a run and then it starts clicking again. I'm tempted to just use the one-way and be done with it but I'd really like to have a front diff. I'm only running 4 cell stock so I doubt it's too much power or anything like that. Any help is appreciated.

mine clicks aswell but i tihnk its normal maybe not?

check your bevel gears and the pins on the CVD's
also check the upper steering linkage..it might be hitting the driveshaft pin.

Not really.

Just open diffbox and adjust bevel gear mesh "closer" using those shims between ball bearings and outdrives. It's all about the bigger gear - it tends to tilt away from the smaller bevel gear under load.

The tricky part is not to "overload" the diff gears by adjusting their mesh.
The same rule applies to diff shimming between the big ball bearings - it should not move left-right, but ball bearings must remain "untensioned" to spin freely.

Yeah, I checked all that. It's definitely in the diff because when I put my one-way in the noise went away. I used the same shims as the ball diff so I don't think it's bevel gear adjustment but I haven't tried to adjust that yet. I'll do that I guess and see where I go.

My pro4 Hara was clicking quite bad, so changed to the same shimming which was on my old pro4 (silver washer on each side of the diff) but was still clicking. I ended up lifting the whole transmission (including cases) from the old car to the new, and now its great! The moulding of the cases may have been slightly different, but i just couldnt get the noise to go away with the new cases.

The shims will be different for different diffs, regardless of whether they're ball, one-way, spool etc.

Every single diff you own might have slightly different shimming so do check it out. When you shim it, make sure the bearings are seated in the recesses on the lower clamshell properly.

Take care - the bearings may move outwards when you put the top on, so physically move them out as far as they will go (there will be slight play), and shim them up until the large bevel gear cannot move away from the smaller gear if you wiggle the diff/spool/ball diff...

This is the surest way of doing things..

THat large bevel doesn't have to be tight on the smaller gear. Not at all - adjust it like you adjust your motor pinion mesh. But you just have to make sure it cannot move AWAY in any circumstance.

If you follow these steps, it'll turn out right every time.

That's the one! Thanks GreaseMonkey!
