F10 530d: Front Shock Strut / Spring / Top-mount Replacement [GUIDE]

*Rear Strut-assembly Replacement Guide here - https://www.beemerlab.org/2020/12/f10-rear-shock-absorber-strut-spring.html*

My front shocks were certainly past their prime up front and over the last few months have really started to bottom out on certain speed bumps. I was also told one of the front top-mounts was starting to go on the last MOT and would probably be an issue next time round, so it was time to give the F10 a mini front-suspension overhaul.

I got hold of a pair of complete front struts taken from a 45k-mile car (I am told, but they are very clean) for just £240. All the parts new and spurious (including my through-work discount) would have been nigh on £400 and lots more from BMW. The used items are of course genuine, so quite a lot of money saved and the struts have turned out to be pretty good so it was a chance worth taking.


The guide I used is by hamanncheese on 5post.com and is pretty spot on, so props to him - I will reference his photos and try to elaborate a little on his instructions. [Original guide here: http://f10.5post.com/forums/showthread.php?t=628336].


REMOVE / REPLACE STRUT:

1. Lift the car and remove the corresponding wheel.

2. Remove the nut holding the top of the anti-roll bar link to the shock-strut using an 18mm wrench. [The nut should come off without twisting the ball-joint, but you may need to insert a T40-Torx socket into the end of the stop it turning with the nut.] [If the stud is difficult to remove from the shock-strut, then using a second jack to lift the hub and prying the anti-roll bar downwards will certainly help.]

3. Remove the lower strut bolt using an 18mm (bolt-head) and 21mm (nut) wrench.

4. Remove the 3 bolts holding the top-mount to the shock-turret using a 13mm wrench.

5. Push the hub down and lift the shock-strut until it clears the bottom-arm and can be removed. [Lift it over the bottom-arm towards the rear of the car. There is plenty of room to manoeuvre it out of the wheel well.] [As hamanncheese says, this step is easier with a helping hand, but can be done solo without much difficulty.]

6. Insert the new strut using the same technique as Step 5.

7. Refit the lower strut bolt first and screw the nut on a few turns. [A screwdriver or other long tool may be necessary to align the strut to the lower-arm.]

8. Refit the 3 top-mount bolts and tighten.

9. Fully tighten the lower strut-bolt.

10. Refit the anti-roll bar link to the strut.


ALIGN TOP MOUNTS:

If the top-mount holes do not line up with the shock-turret, [i.e. if they have been removed / replaced and not fitted in the correct alignment], then they will need rotating to the correct position. Spring-compressors are required.

1. Place the strut on its side with the ring-bracket resting on the floor [as in pic]. This is so it can be lined up against the one it is replacing.

2. Compress the spring on both sides, being careful to mount the spring-compressors so they do not foul the strut resting on the ring-bracket [as in below pic].

3. Loosen off the top mount nut using a deep 18mm socket, leaving it on a few threads.

4. Rotate the lower spring-pan by tapping it round using the notches [in pic]. A hammer and blunt chisel or large flat-head screwdriver will do nicely.

5. Re-tighten the top mount nut and de-compress the spring.


REPLACE SPRING / TOP-MOUNT:

1. Compress the spring on both sides using spring-compressors.

2. Remove the top-mount nut using a deep 18mm socket. [Stand to the side when the nut is fully removed as, even with the springs compressed, the top-mount may still come off with some force.]

*If you are only replacing the top-mount then skip Step 3.*

3. If you are replacing the spring, remove the old one from the strut and remove the spring compressors. Compress the new spring, place it over the strut and seat it in the lower spring-pan.

4. Fit the new top-mount, ensuring the spring is located in the upper spring-pan, replace the 18mm top-nut and fully tighten.

5. Remove the spring-compressors.

F10: Rear Parcel-Shelf Swap / Replacement

The original parcel-shelf was in a sorry state, with several rectangular slots cut in it where Police lights had been fitted. The two in the below picture were glaring at me every time I looked in the rear-view mirror and third, twice the size and facing the rear, could be seen clearly from outside. Despite not being one of the first things to get replaced, it became my biggest concern with the interior and has ended up being the piece that has made the most difference to the car's appearance.

A mint and very clean  replacement was £60 from eBay and came with the speakers, grilles and all trim pieces, handy as mine was missing some.

FITMENT:

1. Remove the rear-seat squab by pulling the front edge up sharply at either side and sliding it forward.

2. Remove the 3 bolts holding the bottom-end of the rear seat-belts to the body using a T45 Torx-socket.

3. Remove the rear-seat back-rest by undoing the 2 bolts holding the bottom brackets in place using a T45 Torx-socket and lifting it vertically up off the upper brackets.

4. Remove the 5 plastic-clips holding the leading-edge of the parcel-shelf by prising the centre-pin out with a flat-screwdriver [or ideally a trim-tool] and then prying the clip out.

5. Loosen both of the C-pillar trims. They are only clipped on and should pop off easily enough at the bottom. They do not need to be completely removed, just loose enough to allow the lip at either side of the parcel-shelf to slide in and out.

6. Slide the parcel-shelf forward partially, pop the seat-belts through the apertures and disconnect both speaker wires. The parcel-shelf can now be fully removed.

7. Swap trims/speakers over to new parcel-shelf.

8. Reverse steps 1 - 6 to refit.

F10: Centre-console / Arm-rest / iDrive-panel Replacement

The centre ash-tray had been replaced with an aluminium plate for the Police-light switches and stuff, so that needed replacing. The centre-console itself, apart from being black vinyl, which would never do, had holes drilled both sides to mount the Police radio / scanner. There was also blobs of glue all down one side, so after a brief attempt at titivating the damage, I decided a whole new one would be necessary and gave a welcome change up to a leather arm-rest!

F10 530d: Correct front seats acquired!

Managed to find the right pre-2013 front seats on eBay to replace the incorrect fit ones [https://beemerlab.blogspot.com/2017/05/f10-530d-black-leather-rear-seats-and.html]. They were for sale on their own, the owner having swapped his front seats for M-sports and was willing to let the old ones go for just £140. They were from a 2011 car with 80k miles and in very good nick, only snag was they were in Northampton, so I removed the passenger / rear seats and did the 6 hour round-trip to collect them. They bolt straight in and bring up no air-bag warnings, so that's problem solved  all round.

The post-2013 front seats I was selling on eBay had attracted quite a bit of attention and a few offers, but eventually someone paid the asking price of £180. This was mainly to convince me to leave them with someone to meet a private-courier organised by the buyer, which was a bit of an inconvenience, but they sold regardless. This leaves me £40 in profit after all thanks to the error, save the fuel money travelling to Northampton.

BMW Response Vehicle Owner's Manual

I can't imagine many people have this in their book-pack. BMW supply cars directly to UK Police constabularies, so this is their in-house user manual for controlling the lights and sirens no less. It shows even the switch-gear being factory fitted with buttons to match the BMW fascia, though I am not sure what level of spec mine had. I guess this is another easter-egg gift that comes with owning an ex-Police car, along with tons of extra wiring and air-con that stinks of sweat...

F10 530d: Black leather rear-seats and door cards WIN - front-seats FAIL!

Lovely front seats do not fit.

Thought I would treat the F10 to a nice leather interior, replacing the tired and fluffy cloth front seats and scratched / dirty door cards, after spotting a complete set from a 2014 car on eBay. I managed to get £100 knocked off the price and drove down to Stourbridge to grab them with a distinct feeling that it was too good to be true. I had to climb nearly 20 feet up a ladder to retrieve them, but they were seriously mint - honestly, not even a mark on any bit of leather - so I parted with the measly £300 and brought them home.

My gut feeling turned out to be right. While the rear seats and door-cards are a perfect fit, the front seats are not. From mid-2013 onwards the F10 floor-pan was updated, along with the mounting-points for the front seats and this means that the runners on my new seats are a couple of inches narrower than on my original 2010-13 seats, which are clearly wider at the base. There is no way to swap the runners, the seats are just too different in design and I will write a more detailed guide on this soon. Annoyingly, the electric plug fits and the motors operate, though they throw up too airbag warnings.

Door cards are straight swap.

Modifying the seats or floorpan to fit is just too much work and will not look very nice, so the only way to go is wait until a pair of front seats for a 2010-13 car come up and try to part-ex mine or at least sell them later. Either way, this could end up costing me more. Regular SE seats are quite thin on the ground for the earlier cars and M-Sports are upwards of £400.

Rear seats fit great.

BMW Part weights + other handy info - BMWFans.info

Thought it was worth mentioning that BMWFans.info that gives the weight of every BMW part. It has all the same parts diagrams as RealOEM.com, but lists other useful information too, including the weights which is handy to know if you are comparing weights to spurious parts, trying to make parts lighter or, like me, sending a part in the post.

http://bmwfans.info/parts-catalog/

I sold an M57N crankshaft and had no way to weigh something this heavy, so was able to estimate courier costs before hand - nice.
