Spoons Posted July 28, 2016 Share Posted July 28, 2016 Right I'm an engineer and work on my own cars for most undertakings. I have a knock on the front right of the Z. Im not about to start describing it as I think it's a complete waste of time as is a video. Im sure most would agree that unless your in the car people can interpret them as all sorts and miss diagnose. I have looked/pushes/pulled and swung on just about everything. Also it's just passed it's MOT today, and me and the owner of the garages I trust spent ages and found nothing. I live in Wakefield, West Yorkshire and would be willing to travel 50 miles. If there is anyone in that radius that thinks they are a big enough expert, and think they have come across every knock and squeak going on a Z. Would you willing to help diagnose this bloody knock. I would pay for your time! It is only important as on the 3Rd of September I am doing a European Road trip that will see about 3000 miles in two weeks done. If nobody can help is there a specialist near me ish. Im on my knees begging (it's driving me mad) Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted July 28, 2016 Share Posted July 28, 2016 I would be looking at the compression rod (banana arm) ball joint. Bank Transfer or Paypal will be fine: 4 Quote Link to comment Share on other sites More sharing options...
Spoons Posted July 28, 2016 Author Share Posted July 28, 2016 I would be looking at the compression rod (banana arm) ball joint. Bank Transfer or Paypal will be fine: I probably know the answer already but.....is there a sure fire way of testing them. The side it is coming from had a new banana arm less than 8 months ago. How often do they fail. I have in the last half hour had the car up in the air with a large pri-bar under the tyre. With the Mechanics head next to the arm. They aren't a cheap bit of kit to just be swapping willy-nilly. Quote Link to comment Share on other sites More sharing options...
350zedd Posted July 28, 2016 Share Posted July 28, 2016 If you cant discover the source of the knock, then its more than likely to be the ball joint as Alex said. You wont detect any wear, but as soon as you drive, it will start knocking. Fit a new arm...if it doesnt sort it you could always sell it on here. Brakes working ok now?

It's a thought I guess, it stings it's got to be a £250 punt. Any experience with the £70 arms of flee bay. I recon that's what was fit new 8 months ago. Brakes were good enough to pass am MOT but not quite to my liking. Im going to try a third bleed with the engine running and if not up to scratch then to the garage for pressure bleed.

350zedd Posted July 28, 2016 Share Posted July 28, 2016 Buy cheap, buy twice as they say, inferior quality balljoint maybe. Anyhow, best of luck...hope you get it sorted soon Quote Link to comment Share on other sites More sharing options...
MattRwebB Posted July 31, 2016 Share Posted July 31, 2016 I've had a knocking noise ever since I've had my HR Had all new banana arms All bushes and joints checked by a GTR and 350z specialist They have said to me it could be the ball joints at the top of my front shocks so that will be my next trial and error job Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

But....the knock I have is distinctive and easy to tell it's from the drivers side front. In fact on first hearing it, it sounded more like there was something loose behind the dash or clocks. This led to windscreen scuttle been removed and inspection of window wiper arms checked among other stuff in that area. Given the ball ache to remove dash I haven't been in a rush to remove. Instead studying this annoying thing every drive. Multiple physical investigations i discovered where I thought it was coming from, that been the inner track rod ball joint. With the engine off and the car on the ground, not jacked, turn the steering until resistance is high and then let go. With no power steering interference it rocks back and haho a knock. Suffice to say I swapped the track rod and the knock was still there.....stay with me I'm getting to the point. I returned to the drivers side track rod and realised the knock was transmitting from the very close proximity pinion gear from the steering rack. I did some googling and found a lot of people were experiencing a similar locality, knock from behind the dash. Their problem was the pinion gear in the rack and the noise was transmitting up the column. There are stories of racks going with as little as 17 thousand miles. This could be worth checking yourself for your knock. I haven't ruled this out but I'm trying the compression arm next. Simply because if it is play in the pinion gear I am two close to a big Road trip to be removing rack and having reconditioned. Second it a lot easier to change the compression arm and the times it knocks I'm not convinced it's from the rack in my case and I have just found a knock when I was looking for one.Hope this helps as you sound to have been cursed longer than I have. 😉 Edited August 2, 2016 by Spoons Quote Link to comment Share on other sites More sharing options...

But £250 are f#*K#+! Kidding and that's a cheaper option than a dealer. Even if there is an unfounded quality suspicion, given they have to pass standards still I doubt anything will fail catastrophicly. At worst the dreaded knock may come back. At £70 and a couple of hours work I'm more than willing to chance it. If it goes again in a couple of years who cares it's a serviceable part, one that can be done three times for the price of the well pricey number. £250 on a rubber bush and a ball joint on a bit of alloy, tut. Again just my opinion. Lol Quote Link to comment Share on other sites More sharing options...
