Glad you got it figured out and BC was helpful.

I have the HF racing jack as well w/ no troubles.

ok so i just went to sears and bought this.

Sears: Online department store featuring appliances, tools, fitness equipment and more

fits under the car at the rear diff, and the 4 jack points along the side rails. I don't think it will reach the front center jack point though. You think i should take it back and get this one?

i think that would reach the center jack point up front. In which case it would take me about 2-3 mins to get my car on 2 jack stands at a time, as opposed to, really long.

I don't think that will reach the front jacking point, you would need something double the length of the harbor freight hydro jack as that is the one I have and leaving clearance aside, would need to be 30 inches long at least.

oh ok. i guess if i want to jack the car up from the front i will just put it on ramps first, or only use the rails. looks like this one will do. Its really light for its size, i'm impressed.

Jeffblue

update: as of yesterday afternoon BC Racing had already shipped my new springs. So, within about 4 hours of realizing thats what i needed, it was already out the door.

nnnn.... the only sears hydaulic i trust is the $20 toy one... which i have in my garage on display.

sears use to have decent jacks over a decade ago but the recent ones leak and dont last very long. the harborfreight one i have is over 3yrs old and no issue on either of them.

Jeffblue

really? the craftsman one isn't that durable? my one requirement is that i be able to jack the car up in one shot, with no.... prejacking

the thing only cost me 120 bucks b/c i had some amex gift cards, so if i only get a few years out of it its all good. i'm gonna need it for this weekend when i replace my springs.

Do i need some kind of cover to put over the jack stands, or can i just put them along the rail at the jack points as is? i have this kind:

kenchan

jeff- well, it could be that the one i got (a long with several car guys on other forums) were just a bad batch, but im not going to be buying another craftsman jack anytime soon.

i think they sell rubber covers for the jackstands, but you can use a towel and such not to scuff up your car if you care. the stands i have have a flat platform at the top and use a piece of block not to rest the car on the railing itself but the little bump behind the rail where the factory jack would rest on. nissan sells rubber adapters too. might want to check with your dealer or courtesyparts.com but they probably wont work with the jack stands you show in that pict.

i also have a rubbercover for my other jack stands and usually it just fits without the wood block behind the railing.

christian370z

I bought the rubber covers to slip on over the tops of the jack stands and they work very well, super cheap from Harbor Freight too! I honestly just use two regular scissor jacks to raise the front end up enough to get the hydro jack underneath and then use that until the jack stands can slip under the car.

worked on installing the 230mm springs today. finally got it right. although this was frustrating, i'm glad i did it myself b/c now i know how to do this. The ride is pretty much the same as with the 210mm springs except there is no noise at all. i fixed it so there is enough preload and the ride height is the same as it was before. When i initially put the springs in and adjusted the spring perches to what i thought would compensate for the addional spring length, my car had like 2 inches of wheel gap. but now all i can say is Mission accomplished.

looking back i think i could have done it in an hour were it not for the trial and error required to get the ride height correct.

Sorry to bring this thread from the dead.... But I have BC Coilovers and I experience this Clunk as well. I do not have after market sways.

It sounds as if the spring is popping in and out in the rear. However I have my Coils with the 230MM Spring and I'm lowered about 1.25. It seems to go away once suspension or car warms up. I Have no clue what it is, but any ideas/input would be great.

Jeffblue

probably not enough preload. When you jack up the car and remove the wheel and the suspension is hanging loose, is there ANY space between the top of the spring and the perch? the spring should be slightly compressed even when the suspension is hanging loose.
