Problem With Coilovers

hi guys, need your advice and opinions on this one..
i drive a 98 pulsar vzr and have had it since christmas, the car came with TEIN adjustable coilovers and i think theres a problem with it..

there was a knock in the back right hand side of the suspension when i got it, but when i brought it back to the garage where i got it, he tighten up a nut that was on top of the strut brace and the knocking went...

there seems to be another knocking from the front and seems to have gotten a little bit worse over time.. it happens when i go over uneven roads or bumpy roads, i checked all the nuts and they are all tight so its not the same problem as the back, also when you lock the steering wheel left, the front left shock/spring seems to "PoP", it only pops once, but is still annoying/worrying, do you think theres a real big problem here? my mechanic said to put chain grease inside the nut, (hard to explain, but where the strut brace is, theres a nut for the shock, in there)

sorry for the long post, but really need your help on this one, what you's think? thanks in advance for the help
 
Probably the spring catching on the spring seat as you turn. Does it have plastic insulators on the ends of the springs ?? The Maxima guys had lots of problems with D2 coilovers doing the same on their front (MacPherson strut like yours)

If the spring is loose on full droop then that could also be causing the knocking on uneven roads.

Do the teins use the original nissan top-mounts or are they tein camber plates?.....it sounds like the top bearing sticking.

hi rowdy, i'm not too sure what the top-mounts or bearings are, :( :confused:
i dont have much knowledge of suspension/shocks at all to be honest.. could you please let me know what these are, sorry for being stupid :(
 
These are Tein pillowball mounts and camber adjustable mounts...

yeap, they look like mine alright, what do you's think i should do? should i go and grease them up, was reading in that maxima forum you gave me earlier mark and some of them mentioned the grease, was kind of like a temporary solution, but didn't fix it!
thanks for the help and keep it coming!
 
Like Mark has said make sure the spring has no up/down movement in it with the car on the ground and the lower spring seats is tight and has not come loose.

Looking at Marks pic make sure the 3 top mount nuts are tight on each strut ( not too tight tho ) and the 4 allen key bolts are all tight as well.

The `pillow ball` mounts in the tein plates can wear and cause a knocking.
 
Just so you understand easier, a pillowball mount just means it's got a spherical bearing in the centre and not a rubber bush like std type top mounts have.

i checked the springs and there is no up or down movement in it when the car is on the ground, the lower spring sits tightly on all of them and has not come lose.. i'll check the 3 top mount nuts again but am pretty sure that they are all tight.. where do i find the allen key bolts??

and if the "pillow ball" mounts in the tein plates are worn? will this cause a problem/further damage? or will it be still safe to drive?
thanks for the help rowdy

come to think of it, my mechanic mentioned that and said to spray grease on it.. from the other forum you gave me, they same that it makes less noise but doesnt solve the problem, would it be a further problem? also, it does seem to make more noise in the morning time when its cold and frosty, the noise seems to ease off after a little while,
 
Well the guys on Maxima.org had problems with D2 coilovers. As I explained in the PM, a MacPherson strut turns with the steering and their problem seems to be that the hard plastic/rubber 'isolator' on the end of the spring wasn't strong enough so it wore through and the metal spring was in direct contact with the aluminum top mount.

Try greasing the central bearing.

Do you have the slots with four bolts for adjusting camber ??

i'm goin to try and grease them when i get home (in college at the mo)
if the metal spring was in contact with the aluminum, would this cause alot of problems? or would it be alright.. i mean will it corrode away at the metal / aluminum
 
also if i want to replace the shock in the suspension would i have to go back to tein and get it from them or can i replace it with a standard shock..
sorry if that seems like a stupid question but i really dont know much about suspension/shock issues.
 
couldnt be the ring nut come slack that holds the shocker into the strut could it. i had a very similar problem to that with a cavalier sri.
 
I doubt that Tein have the same problem with the rubber as D2, D2 have now modified theirs and Tein have been in business longer than D2.

You need to get the replacements from Tein as std dampers won't have the threaded section for the adjustment collars.
