Turbocharger Posted October 15, 2006 Share Posted October 15, 2006 For the last 50,000 miles my gearbox has sounded like it's trying to eat its way out of the casing under heavy load at low revs in all gears, particularly 4th and 5th; it's best described as a rattle, similar to holding the round end of a Bic biro lightly between your fingers and spinning it with the other end. There's also a chattering sound at all speeds under no-load (ie betwen drive and overrun). This worried me when the 'box went in but if it was going to die, it would have done by now. Tonight I took the front prop off and locked the centre diff because it's UJ time again. There's a little more backlash and 'click' as it takes up drive (as expected) but... the rattle and chatter have disappeared. I can now give full beans at 1000rpm instead of waiting till 1500rpm before planting the pedal. Any idea what might want attention? There's plenty of oil in both boxes.

Troddenmasses Posted October 15, 2006 Share Posted October 15, 2006 I can now give full beans at 1000rpm instead of waiting till 1500rpm before planting the pedal. Give it loads. When it finally gives up the ghost, put in a decent box from Ashcrofts rather than a £50 e-blag special. Then you will know exactly what you have in the vehicle.

Guest diesel_jim Posted October 16, 2006 Share Posted October 16, 2006 If you took the front prop off and the noise stopped, id think there is something wrong in the fornt axle? does it make the noise, with both props on, and the difflock in? (so that would eliminate the difflock bits) Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted October 16, 2006 Author Share Posted October 16, 2006 The rattle's definately by my leg. From the sound transmitted by the gear lever it sounds more like the main box than the t-box, actually. Good call on difflock though, I'll give it a go when I've put a UJ in the front prop. (And anyway, it's not an ebay gearbox, it came out of a mate's racer after two seasons of competition... so it's tried and tested, yeah?)

Andy Posted October 16, 2006 Share Posted October 16, 2006 id suspect play in the center diff, if putting difflock in 'cures' it. i have a similar issue with mine, not as loud as yours sounds like it is though. one day in a dim & distant future i may be able to replace the tbox...

white90 Posted October 16, 2006 Share Posted October 16, 2006 John I can get an r380/LT230 at a very good price if you need one it will be a 1.4 one though rather than the 1.2 you fitted IIRC Quote Link to comment Share on other sites More sharing options...

will_warne Posted October 16, 2006 Share Posted October 16, 2006 John, I'd put my money on it either being the centre diff or the bearing on the front output shaft on the transfer box; they have a habit of going. Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted October 16, 2006 Author Share Posted October 16, 2006 Tony - your knowledge of my car's spec scares me slightly... Thanks for the offer but as I said, it's not gone pop (or got worse) in 50k. I'll have a look at the front bearing though, thanks. Quote Link to comment Share on other sites More sharing options...
jjojjas Posted October 16, 2006 Share Posted October 16, 2006 Sorry for the hijack..... I'm in the market for a transfer box for my lt77 if any one has one... no rubbish, must be good. Jas Quote Link to comment Share on other sites More sharing options...
