How to fit new wishbone (lower arm) and track rod end

Hi Guys,

Here's how I changed my front wishbones (lower arms) and track rod ends. Pics are also available in my gallery on the RRS site.

Tools:

Jack
Axle Stand
Locking wheel nut key

5mm allen key
10mm long socket or with extender
15mm spanner
18mm socket or spanner
21mm socket
21mm spanner
24mm spanner x2
32mm Socket
hammer
Torque Wrench
Wire Brush
Thin flat bladed screwdriver

Consumables
Copper Grease
WD40

Torque Settings:
Track rod end ball joint nut - 70nm
Track rod end locking nuts - 53nm
Shock absorber and spring assembly to lower arm bolt - 300nm
Lower arm ball joint retaining nut - 115nm
Lower arm bolts - 275nm
Hub Nut - 230nm
Wheel bolts - 140nm

Torque settings taken from this page:
http://www.rrsport.co.uk/gallery/albums/us...ension.jpg


Time: 2 - 3 hours per side

Prep:
Lower vehicle to access height
Lock vehicle in access height
Apply Electronic Park Brake (EPB)


Step 1
Using a thin, flat bladed screwdriver, carefully prise the centre cap out.

Step 2
Using the 32mm socket, loosen the hub nut but do not remove

Step 3
Loosen but do not remove the wheel nuts

Click image to enlarge


Step 4
Lower vehicle to access height and lock. Apply EPB then steer the wheels full lock towards the side you will be working on.

Click image to enlarge


Step 5
jack the vehicle up remembering to use axle stands to support the weight. Remove the wheel nuts and remove the wheel

Step 6
Locate the track rod end and spray the nuts with WD40. Use a wire brush to remove rust, especially on the nut located on the track rod itself.

Step 7
Using two 24mm spanners, undo the nut on the track rod.

Step 8
Using an 18mm spanner, undo and remove the nut on the hub carrier. If the thread spins whilst you are trying to undo the nut, you may need to use a 5mm allen key to counter turn.

Click image to enlarge


Step 9
Undo the nut on the track rod and mark the point on the thread where the track rod end stops. This will ensure you put your replacement track rod end in the same position as the old one, so your tracking should be almost the same as before.

Step 10
Using a 15mm spanner, turn the track rod enough for it to loosen the thread within the track rod end.

Step 11
Use a splitter tool to separate the track rod end from the hub carrier.

do not break the tool Sad

Step 12
My replacement track rod end was slightly different to the one fitted to my RRS. Not sure if it's a discovery one or a newer item. I just have to take this into account when re-fitting onto the track rod.

Screw the new track rod end onto the track rod, upto the point you marked in step 9 (take into account any difference in length between old and new track rod ends)

Tighten the nut on the track rod.

Wishbone time....

Step 13
Leave the track rod separated from the hub carrier for the time being.

Remove the rear-most undertray by undoing the six 10mm bolts.

Step 14
Spray WD40 on all the nuts and bolts connected to the wishbone. There are 3 bolts/nuts connected to the wishbone, as well as a ball joint with a nut on the underside of the hub carrier.

Here's the end result of what you're working with...

Step 15
After the WD40 has had a chance to soak in, mark out the position of the eccentric cams at both the bolt end and the nut end. I did this by spraying primer around it. This will ensure that the tracking will be fairly similar once the new wishbone is in place.

Step 16
Loosen and remove the four 24mm nuts around the wishbone.

Rear

Suspension Strut

Lower Ball Joint

Step 17
Remove the nut from the driveshaft (loosened in step 2) and push the driveshaft towards the engine so it pops out of the hub carrier. You may need to give it some gentle persuasion with a hammer and centre punch.

Step 18
Remove the suspension strut bolt.

Step 19
Remove the lower ball joint from the hub carrier. You may need to use the splitter again - mine just hammered out.

Step 20
You should be left with this.

If your bolts are siezed inside the bush like my rear one was then having the wishbone in this position will give you a good angle to work with.

I kept turning the bolt and fighting against the springiness of the bush, regularly spraying WD40. The bush eventually gave way and I was able to pull the bolt out without having to cut it.

The bolt had rusted and siezed to the sleeve of the bush:

Step 21
Pull all the bolts out and remove the wishbone.

Step 22
Gather new bolt/eccentric cam/washer/nut

Click image to enlarge


Apply anti-sieze copper grease to the bolts to prevent them siezing inside the bushes.

Click image to enlarge


I fitted my new wishbone in this order:

1) Lower ball joint to hub carrier (and line up driveshaft at this point)
2) Suspension strut
3) Rear Bolt
4) Front Bolt

Once the bolts are through, make sure that the eccentric cams fit in exactly the same place as before. This is where the markings made in step 15 are useful.

Step 23
Hand tighten the four 24mm nuts. I am told that they should be torque tightened once the car is sitting on the ground at normal ride height.

Step 24
Connect the track rod end to the hub carrier. Torque tighten the 18mm nut.

Click image to enlarge


step 25
Fit driveshaft nut but do not torque tighten just yet.

Step 26
Fit wheel and hand tighten the wheel nuts. Remove the axle stands and lower the car.

Step 27
Tighten hub nut to 230nm (used to be 275 but LR reduced it to 230 to put less stress on the bearings).

Click image to enlarge


Step 28
Jack up the car. Remove the wheel and make a notch in the hub nut using a flat chisel.

Step 29
Fit wheel and nuts, lower the car and torque tighten wheel nuts to 140nm


Step 30
Fit centre cap

Click image to enlarge


Step 31
Take the locking wheel nut out of the wheel Whistle Rolling with laughter

Step 32
Raise the suspension to normal ride height and torque tighten the four 24mm nuts.

Step 33
Attach the rear undertray (six 10mm bolts)

Step 34
Get the tracking done.

Give yourself a pat on the back - you've just saved yourself approx £400 Thumbs Up

Thanks Kav that's a great contribution. So much more useful than a manual Bow down Interesting to see you managed it with just the 'customer' jack and no phaffing about with removing fuses, turning on the hazards, opening a door etc etc (let's not start that debate again for God's sake).

Thanks for the kind words Paddi Thumbs Up

I initially used the LR jack to lift it enough to get my 3 ton Halfords jack under the chasis as the side steps make it too low to get the big jack under the car Embarassed

I've found that if you lock it in access mode then it doesn't try to auto level. Either that or my sensors are Censored ed Laughing

I don't fancy doing this on the road side (no driveway) so I'm sadly paying someone else to do mine next week. They're charging for 2 hours work to do it (total of £540 +VAT!!)

I might ask them to do the track rod ends at the same time just for the hell of it. Not sure. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

If youre having the track rod ends changed, it's definately worth changing the inner track rods as well. Inners seem to wear twice as much as the ends. Thumbs Up

About £100 for both sides (plus fitting of course) Thumbs Up

Thanks Chaps - I've got the inner track rods too so when I do my driver's side I'll take some pics and add to the guide Thumbs Up Want to do a DIY job on your car? Check out the definitive 'how to' thread in the technical section Thumbs Up

The inner track rods are around £15 each, and T.R.E's another £15 each or so. If you are interested in buying the kit, it is actually cheaper to buy all the parts individually

That said, I have never had to replace the inner track rods on an RRS. Done hundreds on D3's, but never an RRS...

Just got mine back from the dealer. Took 2 days to replace the front lower arms. Apparently much "swearing and throwing of hammers" was involved. They had to cut them off in the end. Glad I didn't try it myself and also glad it was done on a price so the extra hours involved didn't cost me. Thumbs Up

I asked them to look at the track rod ends. They inform me that they're ok and don't need replacing but I wonder if that's just because they've seen enough of my vehicle for now... Whistle 2012 SDV6 - it's missing a couple of cylinders

2 days? Shocked

It takes 2 hours to replace them... whether they need cutting off or not

Fair enough. Judging by some of their work previously I could see them spending a day trying to undo one bolt... 2012 SDV6 - it's missing a couple of cylinders
