rattle noise after chaing suspension

[jeffreymui]

Hey guys i just changed my suspension to N+ and afterwards, whenever i brake theres a rattle noise on the left front, im pretty sure all the bolts are tight, what would be the problem? would be great if u guys can leave some comment, and also im located in ryde area in syd, any place u guys would suggest to go get a wheel alignment done? since the car is low + I DO NOT WANT TO GO TO THE ONE IN WEST RYDE, cas they tend to break stuff and tell ppl that its already broken blah this and blah that, looking forward to some replies

Loose brake line?
Or a bracket of some sort. Jack the car up n have a look.

Probably a line that hasnt been placed in properly. Or secured.

[jeffreymui]

but i checked and the brake line was very secured, would wheel alignment give this issue?

[OMG.JAI xD]

Very unlikely.

Wheel alignment is only the geometrics of the suspension. Rattles are caused by loose components.

I mean unless one wheel is 20degrees out (which is fcking heaps.) Youll start dragging that wheel and causing a vibration.

If the rattle wasnt tehre before the coilover installation, start looking at things that might have been left loose. OR hanging.

obviously something isnt tight jeff - take it back to the installer....wait that was you rofl !

Its the front , right ? simple. Just gotta jack up each corner and do a once over and make sure everything is tight.

lol stuff u ben hahahahahaha yeah will do it again today

hmm maybe you left a gap big enough between the top hat and the two perches against the spring so it's moving.. just maybe.. or maybe its the pillow ball? hmm rattling... lol maybe even a free bolt somewhere.

If your car is lower now (as I would suspect) there could be some scrubbing issues under braking? just a possibility. also check all your bolts and make sure you didn't leave anything loose.

*bennjamin edit no plugs*

[jeffreymui]

i see thanks guys i'll do it first thing tmr morning to check it out and go for a wheel alignment

[jeffreymui]

just went downstairs to check i think might be the preload perch was pretty lose, and the springs were moving around but im just wondeirng would this make sense? like only happens when i brake

[bennjamin]

its possible. Come over jeff lets sort this out mate.

[jeffreymui]

i still have the rattling noise, any more ideas guys? the 14mm and 17mm im 100% sure its tighten, the preload perch are not lose everything is tighten include the wheel nuts, what could it be?

[bennjamin]

did you check the brake lines to see if they were majorly loose anywhere?
you might have to reused the standard brake line holders off your standard shocks

[jeffreymui]

hopefully its fixed now duno where did the brake line holders gone, when i took off the shock it doesnt have it on them, meh this is crap, u get what i mean ben
