Low car + replacement axles + raising diff advice

Shattered a bearing casing on the dif side as what has exactly happened here.

I doubt that has anything to do with ride height! what kind of tires do you have? Were you doing a lot of stand still launches?

Had my new DSS 600hp axles and Racer X Fab upper control arms installed friday. This was the result.... Sorry for the average photos. Click to enlarge.

Went back to the workshop this morning for a quick check over and we now have a new issue...

The outer CV joints on the axles are leaking grease from the rubber boots even though they're clamped up tight as done by DSS. Not great. We cleaned off all the grease, raised it up 20mm and now will give it a few days to see if they stop leaking. If so, the axles don't like a lot of low. If leakage continues there must be an issue with these axles. Fun times.

Photo's prior to finding leaking grease from CV.

I'm running 9.5 on the the rear with 225 40 tyres. They're cheap and very hard, non grippy tyres.

Also at the time, very limiter camber.

No launches, just drifting in the dry.

Heavy wheels? Assuming 18"s?

Not too heavy...

Work Emotion Kiwamis 18x85. front 9.5 rear.

[bkblitzed]

they're around 20+ lbs correct?

[KONVERTER]

22.8lbs according to the http://www.ft86club.com/forums/showthread.php?t=7535

That is a lot of wheel / tire weight. more than 10% more wheel weight, plus most likely tires that weight more than stock and even grippier... I wouldn't blame this on being lowered... Unfortunately not durable axles which is kind of disappointing.

Are you running the stock diff?

Sigh.....

[JordanWho]

It seems to be happening to a few people with heavily lowered cars.

This is a car set up very similar to mine and his just went a week or two ago.

Yes, factory dif.

I'm more so concerned about my new upgraded axles leaking grease now... otherwise they will go next which wouldn't be ideal.

[KONVERTER]

Leaking grease can just be a boot / seal of the boot. That could be from a tiny hole in the boot that existed before installation even. Far different from a blown up bearing.

Unfortunately the bearing does not seem to be durable at all.

I don't know the quality of the 600HP axles you all are speaking of, but if the boots are not good they will crack and leak regardless of height. Heck, even the stock will too.

Were you getting any wheel hop at all? Ive broken all kinds of rear end parts during hops are kicking the clutch too much (using a multi plate metallic clutch)

[JordanWho]

They are leaking from both CV's so that rules out holes in the boot. They are brand new Drive Shaft Shop axles, possibly the best aftermarket axles you can buy.

Yes the car has been driven hard, but not since the upgraded axles were installed.

[KONVERTER]

Maybe too much grease in there?

Give them a call they probably stand behind their product, at least we hope they do...

My BRZ is not my daily, but when I drive it I am hard on it. It is going to be my track car. I have noticed a popping when I go around corners that reminds me of when I had a locking diff. I was thinking it could be the diff on this car but now it makes me think that it is the bearings in the axles popping... (and my car only has 1800 miles on it and is stock).

Guess I'll take it to a dealer and see if I can get them to warranty something

damn reading all these makes me worried.

I have BC br coils too and I've been sliding my car also. Im afraid when i do word up drift, i'd be stuck there... my car is maxed out on lowered height but i was gonna take off the lock rings to give me an extra inch or so, once im done drifting it and buy a track car, but now im afraid to even slide it...
im broke and don't wanna spend so much on fixing a new car.

I'm pretty sure we're gonna get alot of hate replies from the forum member for lowering our cars but to each their own. I love flush cars and seeing them drift.

I think what also affect him was his massively heavy wheels.
