hi guys. got a knocking noise from o/s/f of car when turning right or going straight, worse when going right and shuts up on a left hand turn. has play in diff but hasnt got worse in 2 years. jacked up car earlier with all 4 wheels in the air and drove it up in second gear and both rear and o/s/f wheels were spinning but the n/s/f wheel wasnt. help please!!!! knackered diff????



its not the outer cv joint clicking/knocking noise

 

Standard front diff is open, so you will only have 3 wheels spinning with it jacked up

 

How do you know it's not the CV?
Remember it'll be sitting at a different angle when you jack it down and the suspension isn't at full travel.
Oh, and I suspect it's the CV

 

if its a cv joint i would check your engine mounts too. thats what kept killing my cv joints all the time trust medue to the engine bouncing all over the place. thought my mounts were good until the engine lifted but not the car lol. they were literally split into 2.

 

i have fitted uprated engine mounts because it kept blowing the o/s/f driveshaft. worked out tonight its the n/s/f driveshaft. took it back off and the inner cv cup was damaged. looks like driveshaft too short and bearings were being pulled out the cup. i bought it off ebay for the o/s/f but it didnt have the cut out for the circlip. so i put it up against the old n/s/f driveshaft and looked the same. so i fitted it to the n/s/f. thinking about it, it must be off a differant car maybe? are the xr4x4 ones differant lengths etc? getting confused now. never had a problem with the original driveshaft that was in there. only got rid of that as i was gonna convert to 2wd

 

well little update. replaced the n/s/f driveshaft with a genuine cossie one and still made the noise slightly but was 10mm longer than the one off ebay!! so today i put the standard front suspension back in and it shut up!! then after about 2 hours of driving it bloody started slightly again! getting really pissed off now!! anyone any ideas??

 

get it looked at by someone in the know then you wont get pissed off with it

 

just a guess.. I've had some sort of problem a while ago and also thought about driveshaft and CV joints but it was the exhaust touching the body in corners and sometimes straight.
Could be also touching the front propshaft from gearbox to front diff
Double check this, and align the exhaust in the middle at that point.
