@thecordlesscarpenter79564 жыл бұрын
Also, for installing the piston nut on top (you know, the one you MUST replace (before releasing spring tension) without grabbing onto the piston itself and ruining your new strut, use a 1/2" drive deep well socket (my new one was a 19mm I believe), and since you can't stick a regular ratchet on there, just grab onto the outside of the deep well socket with a pair of vise grips and stick your Allen driver through the socket's drive hole. If the center of the piston on the new strut (or old one for that matter) does not receive an allen wrench but instead takes a regular socket (like my new ones), just stick a 1/4" drive socket on it (in my case it was a 9mm) right on the end and then put your big nut socket on OVER the small 9mm socket and stick a 1/4" extension through the nut socket's drive hole to engage the 9mm socket. Its a great work around and even ratchets! (assuming you use a 1/4" drive ratchet). Hope that helps the next guy.

Thank you for this video. My '06 Civic sedan likely needs new front struts. The right front makes a clunking noise going over any bumps, even small ones. This doesn't look terribly difficult or time consuming, especially when using a complete replacement strut. Both the dealership and a local independent have now quoted me at over $1,400 for replacing both front struts and alignment. The Honda dealership will be using OEM, which of course costs more than AMP, but the independent shop is only $60 less for KYB's, but they're saying I'd need new mounting brackets, bellows(?), and bearings. I can't even imagine what bearing there is to replace! What's a fair price I should be expecting to pay for replacing both front strut assemblies, as I don't have the tools or confidence to do this myself. Thank you
@BigDog500015 жыл бұрын
When you buy complete strut assemblies they come with all of that stuff, bellows, upper mounts, bearings, springs etc. On this Civic, you can buy complete assemblies from either Honda (online $350 each) or KYB (online $125 each), but the bolts/nuts that should be replaced would need to be purchased separately. As far as installation costs, it varies by region and shops generally charge the fee based on their hourly rate ($75-$150 per hour is the norm) x how long the job should take. If a shop replaces the entire strut assembly the shop should charge less labor per side than if they have to replace the strut with a spring compressor like I showed in this video. An alignment would be another labor charge (typically an hour). If you live in the rust belt, an additional charge for dealing with older rusty fasteners would be appropriate. $1,400 seems about the norm for a dealership but seems a bit overpriced for an independent shop especially if they are using aftermarket parts, at least in my opinion.
@thatpointinlife5 жыл бұрын
@@BigDog50001 Thank you so much. I was just watching your video on checking for a broken engine mount- lol. The car seems to drive just fine. There's little to no dive or body roll when braking or turning. When I push up and down hard on the front end, there's no noticeable slop or softness in the suspension. The alignment is a tiny bit off, though. I can't find anywhere that says that a clunking noise is associated with worn or bad struts, but ball joints, yes. Looking over the dealer inspection report, it seems as though a tech just test drove it and heard the clunking noise, and decided I needed all new struts just based on that. I know they rotated the tires as part of a basic service, but no mention of actually checking for looseness or damage anywhere while they had it up and the wheels off. They just wanted to charge me $1,400 to replace the struts w/o actually positively identifying the source of the passenger side clunking noise.

I just replaced both my struts on my 06 Honda Civic LX Sedan. I did half of these steps and my process was faster but I had to come watch this to double check I installed mine correctly. If you know what your doing it shouldn’t take more than 10-15 minutes per strut. Edit: I took off both windshield wipers and the black cover he’s working under. For whoever is reading this don’t take off the bolts from the top like he is. If you know what your doing you can take off that whole black panel up on top and work with a ratchet and extension way easier and faster.

Thanks for the video! Recently hit a decent-sized piece of metal from debris on the interstate cut a good hole in my tread wear. After it happened I noticed a banging sound when I hit bumps even small ones like someone hitting the floorboard with a sledgehammer, so I think it damaged the strut plus the car has over 300,000 miles on it LOL. Do I need to Jack the entire front of the car off the ground or can I jack up each side independently to get the wheel off the ground? Thx.
@BigDog500015 жыл бұрын
Personally, if I can avoid it, I don't work on vehicles that are only lifted on one side (more unstable). Another issue is if lifting only one side with a jack (and using the designated side lift point), then there is no place to put the jack stand. For this reason I generally use the lift point in the front center and use 2 jack stands (faster and easier than jacking up car twice when doing work on both sides). On these Hondas I only use the designated lift points and I don't get under vehicles unless jack stands are in place.

Random question. When I replaced my front struts I didn’t put the strut under load when torquing all the bolts (top 3 bolts and the 2 bolts that go through the steering knuckle). Been driving the car for 6 months now and have a creaking sound coming from driver side when turning at slow speeds. I’m thinking its possibly because I didn’t torque the bolts when under load. Would I be better off just buying brand new struts again or could I use the struts that are currently on the car but retorque all the bolts when its under load?

It is good practice to always load the suspension before final torque when installing struts. The biggest reason is the rubber bushings should be tightened down in the position they will ride on the car so they don't get twisted up and fail prematurely.

Leaking can be a good indication but they don't always show leaks. If I remember correctly they lost their dampening ability, so it was a very poor ride and it would lose it's composure over bumps. I see this a lot on Hondas in the 150,000 -200,000 mile range.
