specialbikejames Posted October 7, 2009 Share Posted October 7, 2009 Right, got a new to me 1989 127 with original drive train. LT77 box LT230 transfer box. Truck has been well looked after, only 89,000 on the clock. Everything works well 95% of the time. Drove a load of Peak District lanes this weekend- the most challenging stuff I've driven in it. In low box, when the weight of the truck comes onto the drivetrain (steep descents) a repetitive metal on metal clicking comes up through the gear/transfer box. It sounds just like two cogs just clipping each other. Only does this when using engine braking on steep descents. Only ever done it once in High range. Diff lock in or out makes no odds. Makes no difference to how the truck drives- no loss of drive, engine braking remains, no vibration through the gearstick- but obviously something is touching something when it shouldn't be. Gear and transfer boxes seem abit of a dark art, but any help gratefully received before I run crying to a specialist. Jim Quote Link to comment Share on other sites More sharing options...
TJN Posted October 8, 2009 Share Posted October 8, 2009 First thing I would do is change the oil in both boxes. Even if the seller said its just been done. Next look at your propshaft UJ's and give them a good had rattle and then grease them up. Worth checking the flanges on the T'Box for leaks of signs of damage. Next change the oils in both diffs angain look at flanges and check for leaks. Am pretty sure after doing this you will find something amiss , change / repair it and then retest. My 127 made strange noises when I first got it annd they all went away after the oil changes greasing and a UJ change. Good Luck and enjoy life with a 127! Parking is fun!!!!!

specialbikejames Posted October 9, 2009 Author Share Posted October 9, 2009 UJ's and prop sliders are fine. Swivels have fresh EP90 in them and are in good condition. To be fair, I don't know about the T/G box oils so I should change them anyway. But this is not a steady rumbling, and the truck is fine 95% of the time. It's only when It's under severe load that it makes any noise at all. Quote Link to comment Share on other sites More sharing options...
TJN Posted October 9, 2009 Share Posted October 9, 2009 ok, change the T+G box oils and diff oils. Are you new to LR's totally? They can make some noise when going down hill on engine braking and this can seem unusual to new owners. Quote Link to comment Share on other sites More sharing options...
