Thread: Transmission whine

The transfer case in Deafeners is the LT230 and a slight whine from an early model one is perfectly normal. So long as the case is full of oil and the bearings aren't stuffed even a loud whine isn't usually fatal. Replacing a transfer case is a half day job with a mate or two assisting and will cost whatever you can get one for second hand.

So my advice is: get someone familiar with Deafeners to test drive it and tell you how normal the noise level is.

You would need to take it for a run to see how bad it is and where the noiset comes from. I bought a td5 130 with a whine, we'll the loudest whine was in fifth gear. After 5000kms 5th gear support bearing started to destroy itself. I caught in early before destruction and was able to replace this bearing in the box. A rebuilt r380 is about 2200 exchange is sourced in aus. But for the same price (but 6 week wait) you could get an upgraded ascroft box delivered.
