My Brand New Kaaz Diff Is Fcuked After 2km Of Driving

[Shaun]

I cant believe what just happened. I just bought a Kaaz 1.5 way diff, so i gave my old viscous diff still in the housing to a gearbox and diff place, along with the Kaaz diff still in the box with the oil etc. I asked them to change the centres over so i could just bolt the housing with the new centre in the car. I picked it up the next day, they charged me $100 and i took my diff home with the new centre in it.

After installing the diff, i took it for a drive to bed it in and noticed unusual noises even when the car was going straight. I pulled over and rang my wife to see if the oil container (that was still in the box with my old viscous centre) was still full. To my disbelief it was. The diff place didnt fill the housing up with the oil that came with it. So now my diff is f**ked after 2km of driving.

Am i unreasonable to expect them to fill it with oil after installing the centre? They said nothing about the fact there was no oil in the diff. I assumed that the oil in the container was left over; its a metal container, so its not super obvious that the container is full.

I pulled the car off the road, jacked it up and got my wife to bring tools so i could put oil in the diff. After doing this the diff was still extremely tight and was fcuking noisy when driving in a straight line with power to the diff. Im pretty sure its rooted.

Anyway, ill approach the diff place tomorrow, but are there replacement clutch packs or something available for these diffs, or did i just lose a grand?

Also, obviously i should have checked the oil, but do you guys think i have an argument here?

Im so pissed off!

hard to say, i guess you should have opened the top plug and dipped your finger in to check oil level, or at least checked if the oil can was full or not... but when you pay somone else to do something you expect your side of the job to be a lot easier

maybe if it is rooted they will help you out building a new one, i'd take the freindly/upset approch with them.

I know you don't want to hear this right now, but I've never had a place put oil in a diff/gearbox/xfer case/motor they rebuilt. We also didn't check (or think) once and killed a front diff the same way.

Anyway.....ask them to check the damage and they might help with repairing it a little cheaper. But thats about the best you can hope for.

[Shaun]

I know, i really have no recourse. I went to see him today and he got a bit defensive, but we agreed that i drop the diff off and he inspect it and replace/repair for no labour costs.

He said that due to the small amount of driving and lack of tight turns that i did in that short time, the centre will almost certainly be ok. He said that the crown wheel and pinion, however, will be rooted and will probably have to be sent away to be re machined which is about $180.

Anyway, i pulled the diff out and dropeed it off this morning, so i will know by the end of the day. He said they never put oil in the diffs or gearboxes they rebuild, but conceeded that he should have told me that because im not a mechanic and know fcuk all.

Well i suppose i proved him right.

Anyone got a rooted r32 viscous diff with crown wheel and pinion?

Shaun.

[Roy]

I was thinking that the dif maybe ok, but the pinion/crown wheel would have taken the brunt of it. May be a good time to revisit your final drive ration sicne you are now running an uber RB in an R32 GTSt and i expect you are still running R32 gearing rather then the taller R33 gearing?

[Beer Baron]

yep, great chance to get a new CW and pinion. should be fairly cheap too.

[Shaun]

Just heard from the gearbox place. The centre is ok, but the crown wheel and pinion are rooted. Too rooted to have machined, so ill take the opportunity to go the taller R33 gearing. My tooth count is 48/11, so that makes it a 4.36.

Am i right in thinking that the R33 is 4.1 or there abouts?

Does anyone know where i might be able to pick up these gears without purchasing an entire R33 diff?

Thanks guys,

Shaun.

[jas/slo32]

i have a set of r33 4.11 gears in a box at work but i leave for holidays tomorrrow & wont be back till the 6th

[INVRTD]

well, i am gonna learn from your experience mate and remember it ay,

good to hear he was willing to sort a deal out with you, good to see there are some resonable people out there.

[Beer Baron]

32 GTR is 4.1:1 too.

[gfunkk]

so how much is it going to cost you to get it fixed?

good on them for helping you out with free labour

[bubba]

3.9:1 ftw heh

[Shaun]

Well, im looking at between $250 and $350 for a new diff.

Does anyone know what this diff is out of. The guy says its an R33 gtst diff but hes not sure. Its not an r32 but i wouldnt know what other diffs look like.

[swanny180]

Thats definitely not a 33 GTS-T diff... no idea what that ones out of?

[Shaun]

Yeah, thats what i thought.

I ended up getting an R33 diff for $150, so pretty happy with that. I get to change my ratio as a bonus. I actually had three offers of R33 diffs for $150, and a couple of crown wheel and pinion sets for around $70, so its possible to get these things pretty cheap. Just Jap and a few other wreckers wanted to charge me up to $495.
