Ok, so after months of research, asking questions and generally pissing people off, (around here) I finally went and done it. I ordered my springs and adjuster sleeves for all 4 corners. So looking at the FSM, I see all the little widgets and gizmos involved in the strut assembly. So my question is, what all of them should be replaced in the referb? Obviously, some would simply say all. I would think things like the gland nut which came with the new struts would be a gimmi, but what about the strut bearing and isolator? What about the bumpers, which do not appear to be there? Or the strut isolators? Any of you fine people that have gone with adjuster sleeves like the G.C…

M F'er Gland Nut. NEED HELP! 1 2 3

Some jagoff used a 1600 ft lbs. torque wrench apparently to put this POS gland nut on this crappy Datsun designed strut tube (heaven forbid you actually you use a real strut instead of this cartridge) assembly. I have big arse set of channel locks and the strut clamped in my vise below the spring perch and this sonofabitch is not turning. Do they make a socket for an air impact to get this nut off? How do you get these off without destroying your tube and spindle? How deep does this thing go in to the tube? My struts I can put by hand in to the tube and they don't pop back out, would it be safe to apply heat? Whoever thought of this at Datsun is a retard.

Removing Stub Axles 1 2

I have my rear suspension all out of the car and I want to knock out my stub axles to remove my backing plates for a rear disc conversion. At this time I want to replace my wheel bearings and seals. How in the hell do you get those stub axles out? I used my air impart to remove the axle nut, and beat on the stub with my dead blow shot peen hammer last night, and they would not budge. Would PB Blaster loosen them up enough to beat them out? Bigger hammer?

Alignment safety question

I installed some TechnoToyTuning lower control arms this weekend in an effort to get some negative camber to help my understeer issue. I'm surprised that my eibach/tokico setup left me at zero camber in the fist place. The TTT arms seem well engineered by the way, but I started running out of tie rod end link threads before I could get the desired camber. I stopped at 1/2" which gave me only around -2 degree camber, but that seems like too few threads. What is the minimum amount of thread length that I can safely run?

KYB strut boots

Just did the fornt struts and replaced the old torn rubber boots with the KYB boots. Don't bother they don't fit and are a waste of time, effort and money. They have "built in bump stop" which is the only positive, but I'm not sure even that is any good, since its a rubber piece that fits into the top of the boot.

WHY LHD cars have exact same springs as RHD cars?

Hello, I have a question, I looked up earliest parts catalogs both LHD and RHD, springs are exactly same for both.(except Z432,of course this car is RHD only) I thought the reason of front springs are different right side and left side because of the driver and related systems weight( steering/pedals/guages e.t.c), but seems not. Because of what? I think LHD should have inverted springs right side and left side. All S30 have longer spring on the right side than left side, they become same length when installed.Please see attached picture. Long spring means soft(confortable) ? or stiff ? If it means soft, I can see this is reasonable for RHD cars, but I do not get…

Hi all ,as you all know I rebuilt the front end just like everyone else here including poly bushings all around except for the t\c , which is half rubber \ poly . Cut to the chase , I just put new speed rated h , 14 inch federal fomoza tires on my original shelby libres , computer balanced . New outer tie rods , ball joints , end links and tokiko lowering springs and blue tokiko struts . The car drives straight as a arrow but the steering wheel shakes after 45- 50 mph to the point where i will not drive it beyond city speed driving . My suspicions are that I did not torque the ball joints to the proper setting and i think that the steering rack needs a professional to…

Noticed that napa doesn't carry tension rod bushings. But does carry 'strut rod bushings'. Same thing?

stock bushings

I have been doing some shopping around. I want to replace all of the stock bushings in the 240Z that is on the rotisserie. It seems that MSA doesn't have a whole lot in regards to stock bushings, and they probably are not the most competitive on price. Rock auto also doesn't seem to have a whole lot. Black dragon is one option (quality?), are there any better options? It also seems that no one sells a bushing package, only urethane. I am taking this car back mostly stock and don't need the stiffer bushings. Any ideas on where to get the best bushings? I know several board members have had to pull these sets togethor, can you point me in the right direction? Thanks, Charle…

What type of oil do you put in the strut cartridge before you install the shock? I've read transmission fluid works. Or is this something that is not too precise?
