Hi all. Thought I would post here first, before diving any deeper into a problem I have. The car is a 2000 pathfinder with a touch over 300,000 km on the clock. We’ve only owned the car for a month or so and are workin through that various bits and pieces for road worthy. My son (17) bought it as his first car. It is otherwise a great car, and has been looked after well by its one owner since new. It has a notable high speed vibration that comes in at around 80 km/h, and then goes away at about 95 km/h. It’s not a front end vibration, and cannot be felt through the steering at all. This presents as a low frequency “humming” vibration felt through the seat / floor of the car. Wheels (stock pathfinder wheels) have been balanced, and both uni joints on the main driveshaft have been replaced. I have removed the front driveshaft to eliminate anything front end…..and can confirm that there was no change in behavior. I also fitted up a second hand driveshaft I got from a wrecker, which didn’t change the behavior at all either. Before I start digging deeper (diff / bent axles etc), I thought I would just post a query to ask if there’s anything specific to these vehicles that I might want to look for. Do they have a tendency to fail in any particular area that might be causing this issue? Also open to any other ideas. Thanks all.

Dealership confirmed: "VERIFIED CONCERN, TEST DROVE VEHICLE AND FELT VEHICLE SWAY FROM REAR AT HIGHER SPEEDS. RAISED AND INSPECTED VEHICLE REAR TRAILING ARMS AND LEADING ARM BUSHINGS FOUND BUSHINGS TO BE TORN RECOMMEND REPLACE ALL BUSHINGS TOTAL OF 16. PARTS HAVE TO BE ORDER" They quoted $1,879.56 which seems ridiculous. Is there a kit of all 16 or should I order each arm individually from rockauto and then just take to a shop to do the labor?

I had to order everything individually. Finding the right bolts was a particularly painful endeavor. Buy the arms from Rockauto, for the bolts you can either find the closest match at your local hardware store (or online) or get a kit which is what I did but they tend to be on the expensive side. There was an old thread that specifies the right bolts you need. You can replace everything at home but it's 99% guaranteed you won't be able to remove the old, rusty bolts. They need to be cut.

After a long period of R&D followed by successful installs on the initial test group, who have racked up considerable mileage, hardware is starting to make its way out into the world now and we felt it was time to make a thread dedicated to our Pines to Spines SFD kit. This will be the official thread where you'll find a showcase of the rigs that are running our hardware and testimonials from them should they choose to participate in the discussion. Both 3" & 4" kits include: - 2x P2S Strut spacers - 2x engine spacers - 4x subframe spacers - 1x panhard bar drop bracket - 1x steering extension with universal joints - brand new fasteners (OEM hardware is retained) You will need to purchase or fabricate- - Longer brake lines - power steering hardline support bracket - extended sway bar end links - a missing link Note- OEM fitment skid plates will not be able to be retained. You will need to fabricate or purchase a SFD specific set. If you're interested in a kit please DM both @TowndawgR50 & @hawairish in the same message ( you can add multiple recipients to a DM) and we'll get back to you as soon as possible with availability and pricing. @02_Pathy @Ravens794 @Stpickens @Rockit
