I need rear long arm TRE assembly, from ebay photos, it is hard to tell front TRE from rear one. Sellers usually don't give demension, I measured my rear long arm one including ball joints is around 1.32m. I found QHG000040 Delphi is 0.98 m. TIQ000010 looks more fitting. But no length/height info.

Do you mean thread pitches are different? I tested my TRE ball joints (original LR parts), each nut fits both ball joints. I measured both are 1.25mm (5mm for 4 pitches), but knuckle ball joints are 1.5mm (6mm for 4 pitches). How about this after-market https://www.ebay.co.uk/itm/144594619578?

I removed both rod ends by 18 mm socket. What size is different from 18 mm? Replacing assembly is much easier than a TRE ball joint, it saves me time and effort for your info.

Can I adjust the length according to the existing track rod end length?

I found Lemforder assembly unit is not expensive, https://www.ebay.co.uk/itm/273515789757? is right? not sure if I need adjust length.

I consulted disco td5 manual. the rod at the front of wheels is called drag link and another one behind wheels track rod or tie rod, I am confused someone used those terms together. I need to replace driver side track rod end ball joint (behind front wheel). What part number fits it? I aware...

Applogize for my confusing. Yes, maybe it is called axle yoke where ball joints are pressed in.

No, the contacts between ball joints and axle. No, the contacts between ball joints and axle.

Ask AI recommends moly grease, I am going to use copper grease for future in case. Do you use any lubricant and what lubricant do you use?

To get more access to the caliper bolts on passenger side by turning the steering wheel to the most right, I found the steering was moving when undoing the bolts. I disconnected the driver side rod track. I thought power steering won't move, is there a way to prevent steering from moving?

Good idea! When I separated the knuckle, it was hard to loose its lower part. I tried to heat it up, then cool down with cold water immediately, metal expansion and contraction can help.

Do you mean that tool did'nt help you?

I knocked out it. I am trying to push up the upper ball joint with steel pipe by Jack and heat up it at the same time. I suppose 500kg on it, but nothing happened. I am expecting the tool, I wonder if the tool can challenge it.

Thanks! frostythor.

Finally I need to detach knuckle from axle, after I undid lower ball joint nut, I saw a hex on knuckle, do I have to unscrew this, or it is part of the knuckle? See picture. Can someone recommend tools to move out the knuckle and the both ball joints, it seems I don’t need to detach the ball...

Yes, I can do it again tomorrow. When I removed rear caliper before, the socket fits rusty 13 mm bolt straight way.

I saw this link http://www.discovery2.co.uk/brakes.html mentioned front caliper bolt size is 19mm 12-point, but when I tried it, it seems a bit small, I have 2004 landy, should it be 21mm or AF size for the latest td5?

Thank you for your info. I am trying to undo rod end ball joint, I tried 17mm socket is small but 19mm (12 points) one seems a bit bigger? What size is exactly?
