Changing a track rod endThis is not a difficult job to do - I completed the task in around ½ hour.
Featured CarMy 1998 2.5 V6 minifacelift.
Tools and Items RequiredTools19 mm socket (standard)
19 mm socket (deep)
wobbler extension bar for 19 cm socket
18 mm socket
socket ratchet
wire brush
ball joint splitter (available at Machine Mart for about £7.00)
spanner of correct size for ball joint splitter
13 mm socket and 13 mm spanner or two 13 mm spanners
breaker bar or stout screwdriver
Torque wrench
ItemsNew track rod end. Official part description - Tie Rod Kit, part number V0009193094, price £62.08 (Ex VAT and Trade Club Price, April 2007)
Dismantling Lubricant (I use Plus Gas)
WarningsAs ever, do net get under the car if it is only supported by a jack. Axle stands MUST be in place first. I also recommend that you wear Latex Gloves (the same that Doctors / Nurses use). These are available at a reasonable cost at independent car shops.
DescriptionThe track rod end is located between the wheel hub and the central tie rod to which the steering box connects by means of the steering idler. There is already a guide to changing the steering idler -
http://www.omegaowners.com/forum/index.php?topic=90626.0. Very often the ball joints wear and the MOT tester will fail them as a result. Replacing the track rod end is very simple.
PreparationA few days before doing the work, I recommend that you give the bolts on the side concerned a good soaking with plus gas. This will make removal of the nuts much easier.
Before starting the job, find a suitable place to park the car, bearing in mind that you will need to jack up the side of the car concerned. Remove the centre wheel cap if fitted and loosen (but do not remove) the wheel bolts. Please note that the pictures show my car jacked up on both sides with axle stands in place. This is because I was changing the exhaust at the same time. You will only need to jack and support the side of the car concerned. When jacking the car, use a piece of wood between the jack and the car to protect the chassis.
Removing the old partRemove the wheel bolts and then the wheel. To keep the wheel bolts safe, I reinsert them in to the hub having smeared the threads with copper ease. The track rod will be exposed as the picture below shows. Whilst I replaced the complete track rod, you can, in fact, replace the ball joints separately.
The old track rod end
Whilst it remains on the car, look at the way the old rod is fitted. I am replacing the off side (drivers side) arm and there was a letter "R" marked on the outer part of the track rod. The outer part connects to the wheel hub whilst the inner part connects to the centre tie rod. The picture below shows where the letter is stamped on the arm.
The "R" mark on the track rod end is arrow (The "R" does not show that well)
With your wire brush, clean up the nuts that secure the track rod in place. With this done, give them another dose of Plus Gas and set about removing them. The inner bolt requires a 18mm spanner or socket whilst the outer bolt requires a 19mm spanner or socket. Why I do not know. As the outer bolt has a long thread, a standard socket (or at least none of the sockets I had) were deep enough. Therefore I used a deep socket and wobbler bar to remove this. The wobbler bar is an extension for a socket and ratchet which allows the ratchet handle to be operated at an angle. This is necessary to clear the brake disc. The pictures below show the process:

Now that the bolts are removed, use your ball joint splitter to separate the ball joint from the fixing. For those of you who have not used a ball joint splitter before, the pictures below show how. In summary, the fork of the tool slides between the ball joint base and the operating arm makes contact with the ball joint bolt. The tool is then tightened (the arrow in the picture shows this) which puts a constant and even pressure on the bolt. Very suddenly, and with a loud crack, the joint will release sending the ball joint splitter crashing to the floor along with the track rod end.
