Solved - Knocking Suspension

I raised my car using 50 mm spacers a couple of months back. All was fine until I started hearing faint knocking sounds after a few weeks. The knocking has been persistent and seemed to be getting worse. Things got bad after an off road trip last week and the knocking from the front right suspesion became very loud even when travelling at speed along highways. Sounds like 'click-clock'. It sounded like the suspension set-up might just give way anytime.

Was told the knocking is due to the springs and that the solution was to dismantle the suspension and to coil a rubber hose round the spring in order to prevent the spring coils from knocking into each other. Was told that this was a common problem for lifted cars.

Luckily I got a third opinion and managed to solve the problem easily. The knocking was due to a loose nut in the stablizer rod that is somehow connected to the shock absorber set-up. The nut was tightened in 15 minutes ad the problem solved.

Am sharing in case other encounter the same symptoms. Tightening the nut is easier and cheaper than disassembling the suspension to insert the spring coil ruber hose.

Knocking

Sometimes it helps to have another set of eyes look at your rig. I had a knocking in my Sammy and when I sold it, the man that bought is found what was knocking (missing shock rubber). Funny how I had tried to fix the knocking a few times to now avail and never noticed the small rubber missing.

On the flip side, where the you get the lift kit? Any other problems? What kind of tires. Any other mods? I just sold my toy and am looking at buying a new model GV (06/07). I am not sure if I am going to dive in or not. They sure look nice (thought about a new 4 door jeep, but cannot spend that much money yet - who knows maybe I will hit the lottery and get both).

I lifted the front and back by 50mm using block spacers made of teflon/tough PVC material. Had them machined locally. Prior to that, the workshop had to dismantle the suspension set-up to take measurements in order to ensure that the spacers fit properly with the existing mountings. Have not had any problems with the lift other than the loose stabilizer rod nut.

I upsized my tires from 225/70-16 to 245/75-16 Falken Landair AT. Also put in wheel spacers as the car looked weird and narrow footed after the lift. 20mm for the front and 25mm for the back. The result is that the wheels are flushed with the car body. There was some rubbing of the tires with portions of the wheel arch but this is mostly gone now. No big issue and no visible damage to the arch.

I was expecting the larger tires and wheel spacers to result in a larger turning circle but this did not materialize and U-turns at narrow roads seem to be the same as before.

The car looks big and more aggressive after the mods. More importantly, the ground clearance has been upped by 3 inches (2 from the lift and 1 from the tires. The improvement in off-road performance has been fantastic.

Downsides -- noticeably more sluggish pick-up (and probably lower top speed) and slightly higher fuel consumption (from 8.5-9km/litre to 8-8.5km/litre).

Hi Spanky Spangler, not sure which spacers you are referring too. I had the lift spacers fabricated. The wheel spacers I got from the regular tire shop I got my Falken ATs from. These are Japan-made ones, costing abt USD60 apiece. The reason why I used bigger wheel spacers for the rear is because the track (distance in between the wheels) is slightly narrower for the rear The 10mm (5mm per rear wheel) is mewant to compensate for this.

BTW, it appears through trial and error that a 50mm lift is the max that can be done to a stock GV without affecting the camber too much. After the lift the front tires are a tad toed in (not noticeable). A higher lift will require changing the chamber pin. Not sure if one is available or even if it can be done. Also, it will cost.
