Hey guys,

I just had my new Neuspeed Springs installed in my em2 couple weeks ago, and i realized that when i turn (left or right) at 25km/h + i start to hear a knocking noise? not exactly sure where its comming from but i think its from the rear and also when i brake really hard i start to hear the exact same knocking noise? any1 know what this could be???

Thanks for the help in advance

is ur alignment off a bit??

l.d.forget

could be that an exhaust hanger let go.

SunnyEM2

yeah alignments a little off, haven't got a chance to get one yet. But i made an appointment at Woodbridge Alignment heard those guys do a solid job (Y) and thanks for the fast reply guys still have no idea what this could be??

i just lowered my car as well. my problem was that my exhaust was now bouncing off my rear LCA. you may have a similar problem.

while parked, turn your wheels left. check underneath for anything touching improperly. turn the wheels right and check again.

it could be that you dropped it too low and are now rubbing your wheel wells.

SunnyEM2

cool I'll check that out for sure oh yeah i forgot to mention the drop, its lowered 1.5" from the back and 1.75" from the front on stock 185/65/15. ill post up a pic of how it looks asap but i havnt had a problem with the tires rubbing against my fenders or anything but i will check out and see if my LCA are getting hit. Thanks

If you didn't replace the shock, it's probably the shock bushing bouncing around. They probably had a tough time taking out the rear bolts so they heated up the bolt and ruined the bushing.

hey guys i checked everything possible: exhaust hangers, lca's, bushings were all okay my mechanic said install went perfect no problems whats so ever. it almost sounds like its comming from my rear drums? could they be rubbing against the rims because of uneven camber??

chris_v2

No.

l.d.forget

if your asking that question, you have no reason to be touching your car with any tools.

lol at this point im running outta ideas and have no idea what it could be?

sunny, make sure you let us know what the problem was when you find out. i for one am too curious.

SunnyEM2

hey guys thanks for all the help really appreciate it and for sure i'll keep u guys updated. I finally made my appointment at Woodbridge Alignment going in next week hopefully it stops after i get my camber toe and all that stuff aligned........but i highly doubt it lol

make sure the top hats are tight, i had similar noise when mine loosened up

re: scrid3r

i checked the top hats and they seem to be tightened pretty firm, just wondering is their a certain torque value for all the bolts to be tightened at?? (including the top strut bolts?)

D.T.P

I always just tighten it with decent amount of force. Hard to explain, but I don't use a torque wrench for that. Just get it nice and tight with a 1/2" drive ratchet.

Check to make sure your lug nuts are all torqued properly. Check your ball joint, tie-rod ends and wheel bearings as well. If you don't know how to check these things, do a search. If you have a floor jack and jack stands, it's a fairly easy thing to do.

Could also be your front and or rear anti-roll bar bushings or end-links.

my buddy had the samme thing and it was wat DTP said the top hats werent tight enough so when he came off a bump it would knock as the spring decompressed. went home tightened them down all good!!

I'm still waiting on pics!

What brand offers 1.75"F/1.50"R?

PS: Get the knocking issue resolved?
