Work on lower suspension arms

My D4 has, to my surprise, failed its MoT due to:-

Nearside Front Lower Suspension arm pin or bush excessively worn (5.3.4 (a) (i))
Offside Front Lower Suspension arm pin or bush excessively worn (5.3.4 (a) (i))

the Lower Suspension arm ball joints on both sides will be replaced when this work is done.

I'm surprised that these should fail at 44.5k miles, particularly has been gently driven, never towed, and only used off road, gently, probably 6-8 times a year when shooting.

When the work is does should the car have a 4 wheel alignment?

Hiya

Interesting as often wonder how long they should last

Indeed for the front lowers and rear uppers 4 x wheel alignment is required, believe the Hunter system is supposed to be very good

Must admit when I done my Censored rear uppers and had the alignment after it transformed the way it drove

Hope ur well Thumbs Up

firstly, check they checked them properly. there was an edict from MoT central a couple of years back that if the bushes moved but returned to normal position when lever removed, it was a pass. some garages were failing them due to not understanding the nature of hydrolastic bushes.

Mine failed at around the 58K mark and we went the new arm approach rather than just re-bush. Good job as we had to cut the arms to get them off.

I'd recommend getting genuine adjusting bolts as the ones in the kit I bought were sh!te and just failed immediately.

4 wheel alignment is a must.


edit: fit the RRS ball-joints if replacing them.

Nigel, can you hear knocking from the front when driving slowly and dabbing the brakes on and off ? Or knocking when going over speed bumps / corrugations ? If not, I would suggest that they are snagging these prematurely. ( My D3 reached approx 66,000 miles with similar mild usage ) before the knocking started). There is some movement in these bushes even when new.

Mine is now on their second set....first did 44,000 miles and she has just clocked 90,000 now...

It started knocking going over bumps and the arms could be visibly seen moving backwards...the hydro bushes had failed...just replaced them with complete Meyle HD arms from AF....

They can be a total git to do and will often require the original bolts to be sawn off...

As Hardware says buy original oem replacement bolts because they are heavily torqued!

You will absolutely require the car to be realigned professionally....

My 13 plate D4 on 52,000 miles had the front lower arms as an advisory last year on the MoT, this year it sailed through with no advisories and no mentions about the arms!?! Surprised

I could tell they were knocking going over bumps and on our county's wonderfully maintained road network. I think it was more noticeable because I wasn't using the car every day driving for work because of lockdown, WFH etc. Replaced as others have said with the Meyle HD arms set and new OEM bolts, after a full 4 wheel drive alignment by our local indie and it drives like a dream.

All have this on a advisory and going down the arms route. Have a good 4 wheel alignment Center local. What’s the cost you’ve been quoted when not don’t them yourselves?

Mine failed 12 months and 8k miles after genuine arms had been fitted, took it to another MOT test station next day and it passed, it's passed twice since then without anything being done.

Germany 2013 Discovery 4 3.0 TDV6 S Auto Santorini BlackDiscovery 4

Here in Germany they often fit Meyle HD instead of LR or other AM arms,
Meyle is a well known German AM manufacturer for such items.
They last a little bit longer as the OEM ones, but the best is a full 4 year warranty, as the supplier
is fully convinced of his quality.
Maybe worth to check this solution. Companies as Adv. Factors have them
on sale as I found out.
Stay healthy

Just did mine on the drive, last weekend. The hardest bit was breaking the balljoint, otherwise all good. Purchased the Meyle HD version from Advanced Autos, good service as usual. Had the car 4 wheel aligned afterwards - as others have said its a must.

Our D4 has just had it's service and the front lower arms are an amber on the report. Being quoted a giddy £1370 for them being replaced !!

That's far too much.

I paid £1,384 for both lower arms & the prop-shaft to be replaced, which included VAT & 4 wheel alignment.

Get a price from a decent indy.
