Thread: Watts Linkage bushes, Flo-Flex v OEM

Thanks to this thread, I replaced the two outer bushes in the inner section, with genuine parts from my local land rover dealer.

The centre bearing was okay so I left it in. All good now and an easy job once I worked out where to position the ratchet strap to get the body back to centre with the axle. I hooked one end under the lower shock mount on one side, and to the tow hook welded onto the chassis, on the other.

FYI, the bearings were $95 each, ordered on Monday, picked up Tuesday morning. So, finally, a thumbs up for the dealer.

It's a shame these didn't turn out better. They are bloody cheap compared to Factory Land Rover but I guess that's where "get what you pay" for comes from.

Happy Days

Do you think the torque settings are a tad high. Possibly a typo?

What mechanic, without reading the workshop manual, would torque the bolt to that. Exceptionally high.

Thanks all,

Genuine it is.

No, I don't think that the torque settings are excessively high. I doubt it is a typo as its three different figures so would have to be there typos and would likely have been identified and rectified in a TH by now.

The problem is the interior quality product sold by Flo Flex. The genuine items handle the settings.

If your going to a mechanic who is just making up the settings I would consider going elsewhere in future.

Would a mechanic not just tighten it as much as he could and just move on. After all it's not a bolt in the engine block. There are torque settings for nearly every bolt on the car and most mechanics don't check them before proceeding.

For example, did you know the sump bolts require 22Nm or the rocker cover screws are 8 Nm. Who honestly looks at these settings. Wouldn't leave much time for anything else.

Some are more critical than others and I'm inclined to believe this is one for the later.

You are correct, we are not talking about bolts on the engine block here, rather we are talking about bolts in the suspension. Arguably a much more vital component than the engine as it significantly contributes to your vehicles safety in terms of handling and stability on the road when traveling at speed...

I would surely hope that they would not just tighten it as much as they could - there is significant variance in this depending on:

• the strength of the mechanic
• the length of the bar used to tighten - e.g. a longer spanner or ratchet will achieve more torque with the equal force applied

These are also components that are designed to move with the travel of the vehicle. Over tightening can effect this by applying more friction. I'm sure there is technical reasoning and research that led Land Rover to determine that the watts linkage arms to chasis bolts are 155nm, while the watts linkage arms to centre pivot are only 140nm and the central pivot bolt to rear diff is 230nm. I doubt they just plucked three varying numbers out of the air and thought that'll do...

But maybe your mechanics magic hands know better than the vehicle manufacturer...

Yes, I did know that. As I always check the torque settings when I'm working on vehicles. I have the genuine Ford factory manual for my Pursuit ute and the Rave for my Land Rover. There a few minor items that I would not both measuring the torque - such as little brackets, trim pieces, etc., but anything technical I would certainly check.

More people should check the settings. How frequent do you see people complaining about stripped thread in their sump plug or the spinning oil filter housing. Had they checked and used the correct settings these would likely have been prevented.

I carry a torque wrench in my vehicles and use that for tightening my wheel nuts. The custom three piece wheels on the Pursuit are $900.00 per wheel, I don't need them to be damaged by over tightening.

My vehicles very rarely are worked on by anyone else. Last week however, I had a Harrop TrueTrac fitted into the Pursuit by a local diff shop. I took a list of the torque settings for the wheel nuts, brakes, axels, diff internals etc with the vehicle. He already had them, but at least he knew that I expected it to be measured and correct.


But at the end of the day, if I was paying a professional to do a job, I would expect it done to a professional standard. So with a mechanic I would expect it to be measured correctly, including torque settings. I wouldn't be happy with them just guessing valve clearances on an engine instead of getting the feeler gauge out, and likewise I would be happy with them tightening things without a torque wrench.

But maybe I just have OCD with this - either way, makes me glad that I do most of the work myself to the vehicle!

I think you are going to some dodgy mechanics. You also seem to be bringing in non-critical bolts to cloud the issue.

A suspension bolt is a critical component, just the same as a head bolt, etc...

Any mechanic who knows what they are doing should be aware of bolt torque tables even if they do not have the manual values to hand.

What size and ISO class are the 3 bolts the manual gives torques for?
