Hi Chaps,

Apologies for not seeing all the responses - I sold my RRS last year so I don't get on here as much. Well done to those that have given it a go. Thank you all for your feedback regarding the write up Thumbs Up

Just a couple of things to note...

* If your tracking is out after changing a track rod end (ball joint) then you just need to loosen the nut and turn the track rod until the wheels are straight enough to be able to drive to a tracking place. Remember to tighten the nut afterwards Thumbs Up The pic below shows the spanner on the track rod ready for adjustment:

* It is worth having an angle grinder (with metal cutting disc) or reciprocating saw handy in case your bolts have rusted inside the bushes and need cutting off.

hi
have you been given the right track rod end as there are two types depending on year of manufacturer did you get a oe lr or a aftermarket one.
As in your picture the barrel is shorter than the original and I think they shiould be the same
cheers


Hi - yes I was given the (OEM) track rod end for a Disco 3 whereas I had a Range Rover Sport. It just meant I had to take into account the difference in length when putting the Disco 3 one on. My tracking was pretty much spot on when I finished.

Best of luck chaps Thumbs Up

well, job done.
I was lucky, only one of the mounting bolts was rusted in place. Not bad considering the car has 300000KM and is on beaches/ sea water on a regular base.

A big thanks for the excellent tutorial, I couple of point to bear in mind if you're tackling the job :

-Get a quality, large ball joint splitter, mine have to small to fit and i had to use large chisels as wedges.
-the mounting bolts have graduations marks on them, make sure to mark a reference point on the chassis mounts as well as spray painting, you'll get a much closer tracking by the time you've finished.
-pop the drive shaft off from the hub. Makes for a much easier fitting of the bottom ball joint.

-get a helper, this is definitely not a solo job. The parts are heavy and everything has to be pulled and tugged and wiggled to get into place.

- a long pry-bar is helpful too.

once again thank you.

Thats all I use at work on the trucks, normal 3lb hammer wont work? 7lb small sledge does the job.
The only time we use the large scissor splitters is when we cannot get a hammer into the joint

I did my front arms a couple of weeks ago and I also only used a hammer. I've never had to use a splitter in over 20 years of working on vehicles. A good hammer has alway done the job 😃

This website has the best info out there for our trucks!!!!

Ok great thanks guys. Pitcaig when you changed your control arms, did you just use jack stands and if yes did you have enough room to use a hammer on the tie rods? Thanks.

Having done the job, I don't this a hammer alone will do the job but i wasn't work from a lift.

From a jack stand, You would have about a foot space between ground and the hub carrier.
I ended up wedging 3 different chisels (as wedges) and hammering them alternatively.

but if a sledge hammer worked for you Bow down fair dues.

Torque wrench or just air impact wrench

Hi I was wondering if I could just use my air impact wrench to tighten the control arms bolts. My torque wrench only goes up to 150 ft. lbs. and my air impact wrench is rated at 700 ft. lbs. I saw this video where the mechanic just tightens them up with the air impact wrench.

Torque/bolt sheet

I'm a visual person so I made up this sheet with torque and bolt sizes. Hope this helps someone who changes out their control arms. This job is on my next to do list for the spring. I also made a pdf version if anyone wants me to email them one let me know.

Just tighten those bolts as tight as you can i.e torque wrench + socket wrench.

these are going to have to be adjusted by a garage to get your tracking 100%.

Use the air impact on the hub centre nut and the suspension strut nut but don't over do it.

Tie rods

Think its worth mentioning as I do all these jobs, the tie rod ends are handed so buy a pair.
1 is 16mm into the rack the other is 20mm into the rack.

HTH, Roy.
