Hi all, now that I have modified my 73 240 to over 200bhp, I feel that under heavy acceleration the rear diff is moving around. I think there is a uprated mounting available for this can anyone help? Any info would be great..Thanks..

Howdy, I have pulled the rear suspension and diff out and will be putting new bushings (Poly)in and a new cover gasket on the diff is there anything I need to be paying attention to with the diff when I have it open? I have heard to reuse part of the Diff fluid with the new? Fact or fiction. Thanks in Advance

Whoa. I didn't know this rumbling noise was so common. I have a 73 240Z and also have this rumbling noise that occurs, but only at times. My suspension is lowered (about a 4" clearance off the road), so I was always told by mechanics that the angle between the U-joints to the driveshaft/differential is the culprit (because the car is lower than stock). The rumbling on mine however, occurs only at times, which I have no idea why and it can drive me nuts. I do notice that it is most prominant on my Z between the speeds of 50 to 65 mph. So I just cruise between 70+ mph whenever I can. My car just purrs over 70+. However, the officers never believe me when I have to e…

On the e-mail list, there was some discussion regarding replacing/not replacing certain bushings, such as the lower control arm bushings. The consensus seemed to be that they did not need to be replaced if they looked ok or weren't obviously bad (if this is not correct, I'm sure someone will jump in here -no problem) My question is, although my suspension experience is with American cars, is there something inherently different with the z-car that you wouldn't want to replace all the bushings, including LCAs? Or is it more a matter of not having ready access to a press to do the job? And certainly, replacing these without one IS a major PITA, I know! I can't ima…

Dampening oil added to strut housing between cartridge and housing: I recently had to change the shocks in my Z, and the previous owner had changed the shocks about 3-5 years before, and he had not put any oil in the shaft the strut cartridge had gone in. The Cartridge over time had fused to the strut most likely do to excessive heat, and a lack of lubrication. As a result, this made this out to be a very unpleasant experience for me after being in there for a while the cartridge was stuck in the shaft to where it was VERY VERY difficult to come out. In fact one of the four never came out.. even after the strut had been heated with a torch (which was nece…

I have a 1970 240z that I am restoring and improving. I want to improve handling before working on engine. I have purchased so far Eibach lowering springs, rear strut bar and front and rear sway bars. I am now shopping around for performance shocks. I have been looking at Tokico, KYB, Koni etc. I am probably going to stay away from adjustables becuase of the expense. Can anyone give me their opinion or their feed back of what they have found to be the best for this combination. Car is for fun, not daily driver. Mark

My 73 240Z has a pronounced rumble from somewhere aft of the transmission...all 6 u-joints are tight, the tires are balanced and the exhaust is not touching the frame. The amplitude increases as roadspeed increases, the frequecy does too but not very much. I put the car on jacks and ran it in 4th to about 80 mph and the rumble gets quite annoying..... (my best quess is that something somewhere is a little loose allowing just a few thou movement) any ideas where this is coming from..I haven't looked at the rear bearings yet??...also after my run on the jacks stands I noticed a puddle of gear oil under the transmission but couldn't see how it got out...it was about a cup fu…

I just bought a early 74 260. The struts were shot, so I replaced them this weekend. The car looked lowered, but I wasn't sure if the previous owners cut the springs or what. I pulled them out and found Yellow springs behind the krylon paint job they had. Any idea who makes or made yellow springs? The car sits at 24 inches from ground to top of fender well. Thanks

Hi i am actully a 1970 BMW 2002 owner and not a Nisan owner. (ducking from thrown rocks). But i have a question for you. I was told that the strut inserts on the 2002 might be the same diameter as they are on a Z car. So if you can give me the strut insert dimensions i would really apreciate it. BTW, this is for a shortend strut coilovers. thanks, steve
