western Posted November 22, 2022 Share Posted November 22, 2022 Could be the rear UJ is binding & causing the noise, the working angle of the 2 yokes may be to tight & they touch when rotating. Quote Link to comment Share on other sites More sharing options...

Maybe the rear UJ need to be replaced ! But working angle of the 2 yokes are good they are not touching ! Quote Link to comment Share on other sites More sharing options...
landroversforever Posted November 22, 2022 Share Posted November 22, 2022 with the rear prop removed, give the rear output a wiggle and see if its the output bearing. it it moves side to side it could be the bearing on it's way out. Quote Link to comment Share on other sites More sharing options...

You mentioned fitting a lift kit, have you or anybody done anything else, if the prop shaft angles are unequal this could create noise through the universal joints regards Stephen Quote Link to comment Share on other sites More sharing options...

It could certainly create a grinding noise, also check your lt230 output shaft for play, possibly upload a soundtrack of the noise your experiencing for people to listen to. Did you check the prop shaft joints/greased them ? what vehicle is it regards Stephen Quote Link to comment Share on other sites More sharing options...

Snagger Posted November 23, 2022 Share Posted November 23, 2022 1 hour ago, The_rayess said: No its passenger side For clarification, on the right hand side, like the LT230 output? Have you drained the oil through a sieve, or removed the bottom inspection cover? Bad UJs and unequal UJ angles cause vibration and can make noises, but not grinding in my experience - that is likely the prop rubbing on something or bearing failure in the transmission.

Yes it was center diff i swapped it with righ hand side ! No havent drained oil yet, i checked the UJ by hand it makes a clanck noise up and down not side by side ! one side noise i think the sound will be high oon high speed ! No play in the rear output i checked it while the driveshaft installed ! I can move the car up and down with 0 play ! So now i think UJ problem or unequal UJ angles 1 Quote Link to comment Share on other sites More sharing options...

I removed my rear driveshaft! No noise … even at high speed ! So its a UJ or UJ angle am i right ? Quote Link to comment Share on other sites More sharing options...
sean f Posted November 24, 2022 Share Posted November 24, 2022 If the UJ is making a clunking noise in one direction at least one of the bearings have failed, with the prop shaft off have a check on each of the,. I suspect you will find there will be movement in one. Replacement UJ's don't cost to much and relatively light so shouldn't cost to much postage either if you are getting it shipped in, they can be a bit fiddly to change but shouldn't stress any mechanic.

So its a UJ or UJ angle am i right ? Probably, though it is possible that the rear output shaft bearing in the LT230 is damaged. You’ll only really know when you refit the repaired prop shaft. Unfortunately, finding a faulty UJ in the prop shaft won’t rule out a bad transmission bearing - damaged prop shafts put strain and vibration into the transmission, with potential damage to them too. Fingers crossed, though, that it is just the prop shaft. I’d recommend replacing both UJs in that shaft as a precaution, not just one that has play or is seized.

I am not sure that the rear output shaft bearing is damaged ! No play ! I will check it tomorrow because i didnt drive it too much ! I will check both of it !!

steve b Posted November 24, 2022 Share Posted November 24, 2022 As you have a different back axle to the standard fit I'm wondering if the diff ratio's are the same front to back? Sorry if this is an obvious question but just trying to get to know the truck? Steve Quote Link to comment Share on other sites More sharing options...

As 5.29 is not a normal Land Rover ratio. 1 Quote Link to comment Share on other sites More sharing options...
