luggy 13 Posted June 20, 2007 Im at my wits end and have searched the forum thoroughly to no avail. Im getting a rumbling from the NSF, noticeable on motorways at 75 with a slight vibration on the NSF door, coming down the left side of the car, noticeable when slowing down and turnig left and uphill. Ive replaced 1.NSF driveshaft 2.NSF Wheel bearing 3.NSF, OSF brake discs checked the gearbox oil when I changed the NSF driveshaft and the oil was clean. Wishbone bushes and ball joints and track rod ends as well as OSF drive shaft which is less than 6 months old are OK as well as the droplinks and I got the tracking checked yesterday after doing the wheel bearing on the weekend. 4. NSF and OSF engine mounts are OE which are less than 8 weeks old with lower engine mount which is a group N and has been on for the last 3 years with no sign of damage or perishing. It is drive related and considering she's done a 172k with no problems with gear selection I am led to believe that it may be diff? its been like this for the last 3 weeks and Im starting to brick it because Ive got a 600 mile round trip to do this weekend and I'd rather replace the diff before it goes than the gearbox after.

Cheers Sounds daft but try changing the wheel or tyre came across something similar years ago turned out the tyre had a slight high spot which caused the noise and vibration.

luggy 13 Posted June 22, 2007 After spending a total of 3 hours changing the drive shaft, then the wheel bearing and spending money on the parts with still the same problem , it then takes 10 mins and costs nothing to swap the front wheels with the rears and hey fecking presto problem solved , Cheers Andrwn8304 for the suggestion much apperciated. I think I wanted it to be the diff because then I could justify putting a Quaiffe LSD in even though it costs neigh on 500 squid. Share this post Link to post Share on other sites
Andrwn8304 0 Posted June 23, 2007 Np mate, Just out of curiosity, have you got remoulds on or Radials? Never put remoulds the treads have a habbit of coming off the tyre and always get a desent quality Radial it pays in the end. Share this post Link to post Share on other sites

luggy 13 Posted June 26, 2007 Np mate, Just out of curiosity, have you got remoulds on or Radials? Never put remoulds the treads have a habbit of coming off the tyre and always get a desent quality Radial it pays in the end. Found out what the problem was/is. Had a set of eagle F1's on the front and Pirelli P5000 on the rear. Had a problem with the NS rear suspension so I replaced the 2 sandwich plates and mounting bushes. P5000 have done nearly 30k and with the weather getting hotter decided to swap them to the front and put the eagle F1 on the rear. Swapped them back over and got both the rear wheels balanced and the NSR was out and tyre technician guy said there was some uneven wear on the tyre so it seems the suspension problem had caused this.
