When replacing all four wheel hubs, it is advisable to also consider replacing any other components that are located in the same area. Additionally, could you provide recommendations for tools?

Essentially, the prior owner used the wrong lug nuts, resulting in every wheel bolt being totally stripped and irreparably damaged. As far as I know, the only solution to fix the damaged studs is to replace each complete wheel hub. The component number for the front hub is LR023978. The component number for the rear hub is LR012741. I will need to dismantle the whole suspension system in order to access these hubs. Therefore, I believe it is a suitable opportunity to renew the suspension components, as far as I am aware, they have never had maintenance. The mileage on my vehicle is 125,000, and it still has the air struts that were originally installed. I intend to substitute:

    The wheel hubs of all four wheels.
    All four air struts
    Replacement of all four brake pads and rotors

What other items should I substitute while I am there? I presume that the necessary components for repair would include control arms, bushings, and tierod ends, among other related parts. As a novice in suspension, I find the many pieces to be somewhat perplexing. I expect this repair to be challenging for me, mostly due to the lack of available threads or information online on this task. The book states that I will need many specialised instruments, however, all of these items are now unavailable for purchase, and their collective cost amounts to almost $1000. Has anybody successfully finished this task and can suggest more affordable instruments that are effective for doing it?

Additionally, what is the estimated duration for this repair? I am uncertain about the methodology for determining the estimated time required to replace a wheel hub. If it doesn't need a significant amount of time, I will likely take it to my independent mechanic to handle. I anticipate that this work will be very exasperating due to the absence of both an impact tool and an air hammer.

The rear airbags have not been reported to malfunction so far. However, it is well-known that the front airbags are prone to failure, and it is advisable to choose for original equipment manufacturer replacements. Otherwise, there is a risk involved in choosing aftermarket alternatives.TTS. Island 4x4 UK offers competitive costs, a wide range of options, and efficient shipment.
Apply DC111 / MOLY COAT to all O ring connections to maintain rubber softness and avoid cold-induced leaks.

Indeed, I am aware that the rear air bags are distinct from the shocks. Are you suggesting that things are very resistant to bullets? Regarding the front, my intention is to do a complete assembly, including both the shock and the airbag.

Acquire fresh ABS wheel sensors, since they are susceptible to damage and difficult to extract and repurpose.

If you are unable to get the appropriate servicing tools to detach the original front knuckle from its bearing/hub (in order to reuse the knuckle), it is advisable to purchase replacement front knuckles.

While I do not officially support this, I must acknowledge that this is a cost-effective alternative. Two front left-hand and right-hand steering knuckles for a Land Rover Range Rover from 2010 to 2012 with a V8 5.0L engine are available for purchase on eBay.

During the process of rebuilding the suspension, it would be advisable to also contemplate replacing the axle shafts. Rockauto.com and other aftermarket providers offer a variety of options from different vendors.

Typically, the rear bags are not modified, but the front struts, along with new bags, need be replaced. The original equipment manufacturer (OEM) options are Delphi or Bilstien. For the most competitive rates, choose Island 4x4 UK.
The front knuckles seem to be an excellent option, as they will undoubtedly save a significant amount of time. I would recommend applying lubricant to all exposed metal surfaces to facilitate disassembly, if needed, within a span of 5 years.

Thank you for all the advise. To save time, I purchased pre-assembled secondhand knuckles and hubs. Approximately $100 for each corner on eBay. All components were sourced from an L322 model with far less kilometres than my own vehicle.

Now, my only task is to replace each knuckle unit without the need to concern myself with detaching the hub from the knuckle, a process that requires many specialised equipment. I am concerned about the process of removing the CV axle from the knuckle, since the text indicates that it requires specialised equipment. Evidently, it is a frequent occurrence for the axle and knuckle to get fused together. I will address this issue as it arises.

Regarding the front air struts. How can I determine whether my car is equipped with the higher-priced continuous damping system?

Inspect the upper part of the air shock for a connection, specifically a bolt, with the wire harness connected to it. If you find this configuration, it indicates the presence of the constantly dampening system.
Otherwise, it is just the conventional air strut.

If you repair both front axles, you may avoid using the special tool by removing the old knuckles while the axle shafts are still in the hub(s).

Mount the new axles into the 'new' hubs (I coat the new splines with anti-seize paste to make future removal easier, but some disapprove of this practice).

An axle removal tool that is not specific to JLR vehicles may be purchased on Amazon for a price around $100. However, in order to use it with a full-size hub, you will need to get five M14 x 1.5 x 40mm attachments. Please refer to the picture below for more clarification.

Exclamation marks! It is crucial to exercise caution to prevent any harm to the end of your axle if you want to reuse it.

Based on your previous experience, did you have any difficulty with the axle being firmly attached to the knuckle? Did they readily separate? The problem with that tool is that I believe I need to insert it into the wheel studs in order for it to function. I assure you that all of the wheel studs are totally damaged. I am unable to attach the tool to my studs.

I intended to purchase an electric pneumatic hammer to facilitate the detachment of the axle from the knuckle. However, I am uncertain if the components will be firmly glued together. Being in New Orleans, there is no rust present. I am optimistic that it will be easy to disassemble. I have no inclination to purchase new axle shafts. It will incur a significant additional expense.

If you can successfully remove the big axle nut using an impact gun with a 36mm socket after releasing the punch tabs on the nut, and also remove the two large bolts that link the knuckle to the strut, you will have enough flexibility to determine if the splines of your axle can be readily removed or not.

Striking the axle directly with a hammer will most likely make it unable to be used. Using a small section of 1 1/4 inch wooden dowel (available at stores like Lowes or Home Depot) as a buffer between the impact surface and the axle may be effective, but it is important to note that removing the axle may be difficult due to its tendency to resist sliding out easily.

For what it's worth, I am now changing the front wheel bearing on the driver's side. I needed to use a 20 tonne press to remove the previous bearing from the knuckle, using the appropriate seven piece JLR shop tool. If you provide the knuckle, you can consider locating a nearby business that is willing to replace the bearing for you.

Wishing you the utmost success.
