exlpoded cv joint
 

We were at the 1/8 track last night great weather managed a 8.31 with a 1.90 60ft and the next pass

that 1/8th mile is good for a high 12 second run, even with a 1.9 60" ...not bad.

Were gonna see a lot of stuff start breaking now that the strips are opening up.

Plans for upgrade?

yeah I will defiantly upgrade, but with a used stock one being $150 ill do that for now. I also wanna be sure why it broke if I over angled it I don't wanna destroy a new set

How much power you running?

266 on a dyno dynamics if u figure the 7% everyone seems to swear by its like 285

How much axle tramp was there?

none when I hit 2nd it gave up

Axle tramp is when you've wound up a leaf spring, our suspension style suffers from wheel hop.

similar effect, terminology when describing something can be important.

looks just like mine only diferance is my inner race is onle nicked in a few places and the outer plunge cup shows almost no wear and no damage...

what caused it? do you think it pulled out enough to snap?

I'm going with shock on this one.

What kind of slicks are you running?

I snapped my axle in half today ! what is going on here !! haha

I'm running ventus rs3 245
@Fallen51 u snapped the shaft its self??

Robert I know your car is pretty bare and probably makes a lot of sounds like any fast track car should...........but does the nicked area you speak of causing any clunking when you first engage a gear while turning?

yeah for 3 days prior to failure I thought the brake rotor/pad combo was clicking who'd a thought? I me we drive it HARD but I'm pretty smooth...don't speed shift etc... started taking off "normal" and bang!

Haha yes which I cant believe.. I forgot to grab a pic before the tow truck came. It broke on the diff side right at the boot. I can grab about 2 inches of the axle before the joint.

I looks to my that you may have had some grease failure. Robi did you change out the grease to something a little more high performance? How did the grease look? runny like eggs?

Grease still slick and sticky...not paste like thick...but not runny eithr...

Usually when that happens in the buggie stuff it's cause the grease is done. It's not looking to good for the longevity of some of the parts on these cars.

we use this it's the best.

I have yet to truely beat on my car yet, no track days or burn outs, and I have a noise occasionally when I back up then go forward. It sounded like a junk cv but I figured I was imagining it. Guess I better check it out.

Looks like the driveshaft angle is a bit severe. How much is the car lowered?

You might have to raise the diff centre.

I am not slammed by any means, but it is about 1 1/2 inches

My brother said the car squats really hard on launch amd when I shift so I am going to stiffen the coils up and see if it does it again but DSS axles will be happening

Can you share any info/threads about anyone doing this?

My 86 is set up for drifting which is also slammed with a lot of camber and I also just broke a bearing casing like in the OP.

I'm looking at the 600HP rated DSS axles but want to try and lower the diff to reduce any additional strain.

Usually it requires cutting the subframe and floor enough to raise the centre , then reinforcing and replating it all. You also have to ensure you have clearance for your tailshaft.

Why does your car need to be slammed for drifting? It is about driving isnt it? Not hard parking?

This has me nervous about my track trip next weekend. I wish we had $150 used stock axles up here

Amen

I got my used axles off eBay, and have not had a problem since I put it back in all I did was stiffened the coilovers when I drag race to keep it from squatting. This axle has at least 20 passes on it

:bellyroll:

I can for certain trace mine back to a very STUPID thing I did last summer. On the side of the road I turned the wheel fully to the left, revved to 5500, dropped the clutch and did some rather tasty donuts ...... and man was it fun and nice and smoke and "kool". And yes I had axle hop like a mofo.....

Thats when I started noticing a VERY slight knock when taking off NORMAL from a stand still and making a slight left. It was VERY subtle and got worse and worse. Doesn't do it going right.....only left. Its gotten progressively worse and Friday we are swapping out the shaft on the drivers side.

Like all noices I'm prepared for it to be the opposite side and for it to be the DIFF. If its the differential....GAURD here we come !

The amount of people seeing this has got me worried, I my car a bit for the time being!

What is your rear suspension height?

Has anyone broken the driveshaft shop "600hp" axles? I know they make good DSM parts, but the 3000GT axles they made were weaker than stock.

I just ordered these. Interested to see how they will go.

Mine will probably go because I'm running a lot of low and the car gets driven pretty hard.

Google crawfords build that was the first thing that broke in there car was the cv joint Im sure someone will make a better designed one that can withstand the power

From what I have read it seems to be close to the same they used in the s2k if that's the case it will be able to hold up to more then it is rated for .

I hope so.... will let you know :popcorn:

Two more days till race day!!!!

Is it only boosted or really low cars that are breaking CVs?

"Abusive" launches on sticky tires too, couple autocrossers have popped 'em.

its all of the above and what the guy above me said.
