Rbailey182 Posted March 30, 2017 Share Posted March 30, 2017 Soooooo, Being the budding DIY Mechanic I thought I was, I would have a go at replacing the Lower compression arms today. I have a list of jobs that need doing such as front bearings, discs/pads and bolt on/off stuff I never normally have an issue with. So that being said I ordered a new front set of Banana arms ( sadly couldn't afford OE ones ) and the bearings this month with the intention of doing the discs and pads next month when funds allow. I proceeded to jack up the OSF wheel first, got the axle stand in place and popped the wheel off. Now, after watching a few random videos on YouTube about 350z work in general, I knew that I would no doubt be faced with seized bolts. However, I was not ready for it to be the very first bolt Yes the ABS sensor bolt. Well, I say it was seized, I used a 1/4" drive ( so no major leverage) and it felt like it was coming loose. THEN, Snap! Great start to the day. Anyway I decided that I was not going to get frustrated and angry and I would deal with that issue later. So onto taking the calipers off. Struggled like hell to get the bolts to crack but after about 20 minutes ( and a brew) I got them both to crack with no issues. Suspended the caliper and proceeded to take off the disc. Then came the joyous 4 bolts of the bearing. 3 of them came out really well. The 4th however, the one by the banana arm was of course now not accessible by sockets!! As I had only jacked up the one side at this point I just struggled on with the longest spanner I have in my inventory and after some perseverance i got that one to crack as well. ( Its probably worth mentioning at this point that I had applied generous amount of penetrating oil to pretty much any bolt that I was going to be addressing). So far due to extremely tight bolts and sore knees/back ( and the need to drink copious amount of tea ) I had been at this job for 2 hours. Anyway, I thought now would be a good time to get the banana arm ready for removal as I had a good amount of access to it with the bearing being out. First things first, Split pin. Yep it snapped.............. I was starting to get a bit more annoyed now but I though no worries I will get my small punch and start to knock it through so that I can pull it out the other side. Start seeing some results then my mate decides to surprise me by kicking my feet. I of course jump and snap my punch with a small piece now lodged in the split pin hole. I am fuming at this point and my friend quickly departs. So now I spend an hour carefully and methodically filing down any protruding pieces of metal ( not hitting the thread) so that I could at least get the nut over the hole and off. All the filing done and by this point the penetrating oil, having several applications, had been on for a good few hours now so I tried my luck with the banana arm nut that is closest to the bearing. After struggling with it for 10 minutes I finally hear that creek and a joyous moment feeling the nut turning and turning and turning and not doing anything else. Turns out that the creek was in fact the bolt going into the banana arm and not the nut as I first thought. I tried every way how to put some type of pressure on the arm to give me what I needed to get the nut loose but it was just having none of it. That means now that I have to grind the nut/bolt off in order to get this free. I felt at this point that I should stop while the assembly was still intact and admit that I need to get a garage to do this part of the job for me as I don't have the correct tools or equipment. I had been going for 5 hours at this point and thought enough is enough. It took me about 20 minutes to put in the new bearing and reassemble everything else to which I just laughed at myself. So now I'm left with the dilemma of needed the arms fitting by someone who knows their way around the Zed suspension and wont be surprised by anything ( probably having seen it all before ). I really hope there is someone near to Cannock or in the Staffordshire area who wouldn't mind fitting these for me ( obviously paid work ). If there is anyone who can, please let me know, or if anyone knows of anywhere near that I could get in contact with that would be great.

greasyphil Posted March 30, 2017 Share Posted March 30, 2017 i wish people would stop using the word Banana , call the parts by there correct name, cutting seized nuts with a disc cutter is normal, i think Z's are a nice bit of engineering compared to a Merc Quote Link to comment Share on other sites More sharing options...
Gassy Posted March 30, 2017 Share Posted March 30, 2017 Hi,wish you would have posted earlier I would have been more than willing to help you fit/fit them for you (at no cost).I wasn't at work today and you only live down the road.I feel your pain last week I fitted on my Zed some unrated brakehoses all bolts seized on the front,then when it came to the rear I managed to break a front to rear brake pipe(again corroded) a frantic trip to CES in Cannock to buy a hand pipe flaring tool,all sorted now thank god.Sadly back to work tomorrow,working the weekend and on holiday next week.Would have been nice to have helped a fellow Zedder.Glen Quote Link to comment Share on other sites More sharing options...
Rbailey182 Posted March 30, 2017 Author Share Posted March 30, 2017 i wish people would stop using the word Banana , call the parts by there correct name, I could have called it "the biggest annoyance to enter my life so far, upsetting what is a truly enjoyable car to drive with a constant knocking that is consistent with that of living next door to a newly wedded couple"?? That took too much effort to type and as the whole thing was long enough in the tooth, me using banana instead of Lower Compression Arm was a justifiable exchange I think Hi,wish you would have posted earlier I would have been more than willing to help you fit/fit them for you (at no cost).I wasn't at work today and you only live down the road.I feel your pain last week I fitted on my Zed some unrated brakehoses all bolts seized on the front,then when it came to the rear I managed to break a front to rear brake pipe(again corroded) a frantic trip to CES in Cannock to buy a hand pipe flaring tool,all sorted now thank god.Sadly back to work tomorrow,working the weekend and on holiday next week.Would have been nice to have helped a fellow Zedder.Glen Appreciate that Glen, What colour year do you drive?

Rbailey182 Posted March 30, 2017 Author Share Posted March 30, 2017 Silver 2004 Private plate *** 3502. I'll keep an eye out. I haven't seen many Zeds around this area. Think I have counted about 5/6 mixing up the 350s and 370s Quote Link to comment Share on other sites More sharing options...
