Just use a pair of side cutters on the threaded part of the shock shaft.

Nope, I was talking about assembling the shock body and shock cap, and disassembling...

I also use side cutter for the ball ends.

Using a towel (I prefer the micro-fiber stuff) you can get more than enough grip on the shock body to tighten the shock caps. If you need a little more grip on the cap, insert a screw driver through the shock eyelet.

If you use tools, you can easily over tighten the cap and damage the bladder or make it not seat correctly.

So just snug up the shock cap?

I don't think I can get quite tight enough by hand.

Thanks

Just a little more than hand tight? How tight are you wanting to get it?

yes hand tight is fine... you can also feel the pressure on the bladder helps judge the tension... and like Rocco added, using tools can damage the bladders.

The front bearing failure issue happened to my friend today during the main, the pinion bearing fell apart and melted the diff housing. We are not sure if it ruined the gears or not...but that honestly worries the hell out of me.

Yeah unfortunately my pinion melted its way through the gearbox casing when mine failed last weekend, ring, pinion, bearing and casing are all toast - Even worse that everyone seems to be out of the ring and pinions at the momment.

Same thing that happened to my buddy today except we have not seen the gears yet. This needs to be fixed or something, because it is an issue...i love this car, but i hate being afraid that it might do that to me during a main and cost me 60+ dollars.

haven't had a problem yet and don't except to... because I've reed most of this thread checking out all the tips. maybe others ---->you and ----->you should do the same. The 808 IS ROCK SOLID!!

and BTW Im still using the rubber seal on the bearings also!

Actually I maintain my car more than anyone else I know, it always looks as new as the day I built it and always has bearings that feel even slightly gritty replaced, anything thats worn or scratched gets replaced - So its definetely not maintainence. I haven't changed my pinion bearings, only because there was nothing wrong with them and any time I took them out to clean them, or when I initially built the car the retaining screws where always loosened off slightly, as per the instructions.

What I did find however was two lovely impressions of the driveshaft pin on my front centre drive cup, also the same one that had the failure. If there is a design fault with the length of the driveshaft, causing this to impact any shock to the pinion bearing then only regular replacement of the bearings themselves would delay any failure, but even that is not gaurenteed as far as I am concerned.

What affect to handling does using the lower shock mounting holes as opposed to the upper shock mounting holes on the shock towers?

What are you doing with the gritty bearings... you can remove the seals and spray them with Methanol Hydrate (8bux at HomeDepot for a gallon) using a quality spray bottle, spray clean and re-lube with AfterRun Oil. Removing the seals and using the stream setting continue to rotate the bearings until the grit is out!! The afterrun oil helps wash away the fine grit and lubes them at the same time! Ive been doing these things with some others (that have been mentioned in this thread) to keep the car running prefect! My 808 now has 4 healthy race weekends on it (absolutely no bashing), and still is like out of the box. just a thought? stop pinning your landings and maybe you wont warp the front drive shafts... "design fault" yeah right!!

Me and my friend both have at least 4 races on our 808 ( i have more), we both maintain our cars. I am lucky it did not do it to me, when i went to clean out my car the other day, the only bearing that was seized up, was the same bearing that ruined 60 dollars worth of parts for my friend. We are racers, not bashers, we understand how to tighten screws etc....the screws holding down the bearings in the diff are fine.

The potential damage of this is what worries me...if it was a minor fix, then honestly i would not care
