Rear End Knock Over Buump Help!

[sct911]

I had a knock when going over bumps n humps , turned out it was the spare wheel jumping up and down , isn't really secured

[jas98]

all fixed, turned out it was right rear wheel bearing and hub, the bearing was spinning on the hub and had allot of movement. plus also allot to do with the control blade bush's, I replaced them with whitline and now iit handles great and no more noise, just a nice quiet ride....beside the squealing brakes!

was this noise over stuttery bumps...with most of the noise obvious on the up travell? Ive got the same traits on mine (BF2T)... hav also changed everything except front controll blade bushes...ill check the bearings & Hubs. Only thing that differs to mine is that my noise tends to be on both sides...but more so on my passengers side

[jas98]

yeah sounds exactly like mine did. could also be your shocks?

although I noiw have a wooping sound that comes and goes....next adventure haha

but if you blade bush.s are old id recomend replaceing with whitline, they work great

[Kroozin]

hey jas.. how come your replacing your drive shafts?

[jas98]

at the time there "seemed to be some play " in them, but now that there off they seem fine, so ill regrease em and keep em as spares lol as I already brought the new ones

altough I have no idea if there still the original though

[SipposBFT]

Def not shocks Jas... I replaced the standards with Billies... along with all the bushes & knuckle joints @ the same time... imagine the frustratiion when the noise was still there!!!!! Was hoping it was the shocks as there was minor play in the standard bushes. My mate who used to work @ Peter warrens says the drop links can also produce movement over time & ill give these a check as well...man I love my car...but theyre a pain in the rear...pun intended ...

[jas98]

hahaha yeah its a pain and sometimes you wonder why you bother , when you still hear that noise. happened to me a few times and when I hear the noise I want to drive into the nearest tree/pole/anything that would prevent me for trying to source out the noise for the next f*cking week lol

Did you repplace the control blade bushs? and also hows the wheel bearings?

also when you say knuckle joints do you mean rose joints? is so were all 6 (4 small and 2 large ones) repalced?

cheers

[SipposBFT]

yeah..think sum call them rose joints... pedders call em knuckles... no didnt replace blade bushes... they assured me they dont cause knocking noises... was very minor play in them... but not enough to warrant changing... how did you find the play in the wheel bearings? Leaver the wheel side to side?

[jas98]

Well, when I had car jacked up there was no movment in wheel bearings but after I undon the large nut you could tell there was way more movement then there should have been, im guessing when the weight is on teh bearings it made it show the play...if that makes sence.

alls I know is the control blade bushs were brand new makay branded oem style, but then still did not like how the rear end was handling so decided to change the control blade bushs again with whitline ones and wheel bearings.and it stopped makeing any knocking sounds. and firmed up the arse end nicely

also the OEM control blade bushs are known to cause knocking sound, there a sh*t desighned bush from factory, have too much of a void in them, if you can update them to whitline etc, even if it dont cure the knock you will be glade you did it!!! trust me
