RA28 Diff - They keep blowing - What can i do ?

[thechuckster]

yeah - T-series has lasted behind my 18RTE, the thing that's suffering is the gearbox not the diff or axles. Can't see an 18RC making anywhere near the output of my turbo variant.

[whatthe?]

It took my 245rwkw MA61 6 months to destroy a T series open diff (and I wasn't nice to it either). To go through that many with 75kw seems a little odd. I'd take the advice of others and have your current diff/housing looked at properly before forking out mega bucks for something completely over the top for your requirements (of course if an engine convo is on the cards for the future, then why not?)

[Sam_Q]

why did your ma61 have a T series in it?

[whatthe?]

Me not know, bought it like that. Sure was a surprise when we tried to put the replacement F series diff in it! Much swearing and a new rear sunframe later and it was all F'ed up

[Sam_Q]

it had a solid rear end in it? I dont know if an irs T series

[whatthe?]

No it was IRS, some of the XA6X celicas had T series IRS, as well as some of the XX celicas

[Sam_Q]

well there you go you learn something every day. Sounds like someone blew a diff and could only find a celica one

[whatthe?]

That'd be my guess, big job to change a whole subframe just to save a few bucks on an F series diff, but meh, who knows what they were thinking

[KZN130_Surf]

Its the center that blows, but each change ive done has been the entire rear end...

This diff is just really loud... Possibly clutch problems aswell...

[TA-022]

how many diffs?

1-2 id say you had a tired one and were unlucky to put another tired diff in.

3 + diffs id say your rreeeeeaaallyy unlucky or there is something in the driveline that is transferring toooo much load to the centre??

[hemi twofifteen turbo]

well he did mention heavy duty clutch.. maybe that's it?

[KZN130_Surf]

Im on the 3rd now, its only been like 4 months since my last one went...

Yeh... The clutch was a playing up a while ago.

[wilbo666]

I've always found that putting oil in diffs after putting them back together tends to make them last sooooooo much longer...

I'm with stupid
