Trek Marin 7 crank set upgrade
Hi so I can hear clicking noises and feel tension on the left pedal when I apply pressure, my last bike this happened to the pedal fell off so I've found the exact replacement (Shimano Acera FC-M371) I want to replace the bottom bracket, the crank set states it comes with a square taper fitment but havnt a clue what this means, any ideas on a bottom bracket or the correct size, this is why I just end up buying a new bike but I don't really want to this time, any help would be great thanks

Kops and Retul don't have a way to figure that.

Sorry.... I'm being a butt.
This is sub-forum is about how you fit on your bike. Not about maintenance or fixing it.
You really should be in the Bicycle Mechanics sub-forum

Don’t understand what you mean when you say ”feel tension on the left pedal”.
Pedals falling off is unusual. They usually work themselves tighter.
Crank arms falling off - particularly left - is more common.
The m371 is available in different tooth counts.
Unless you know how to check your chain for length, make sure you get the same.
To swap a square-taper crankset in good order you need a crank puller.
And to mount one - If you’re new to bike mechanics - I’d recommend the use of a torque wrench. Insufficient torque at installation can kill a square taper crank real quick.
Much as I like to encourage people to DIY, I think you could merit from taking the bike to a shop. You’d get a safer diagnose on what’s actually wrong and what to do about it.

Hi I took it to the shop to get looked at, the guy said he took the crack off and bootom bracket and cleaned it all, said it looked good but I rode away and withing 15 mins the clicking was back, its on both sides now and sounds like a car indicator, the tension I am talking about vibrates my foot like it creaks when I pedal

Well your question doesn't seem to be related to the discussion intended for this sub-forum, which is stated near the top....
Fitting Your Bike Are you confused about how you should fit a bike to your particular body dimensions? Have you been reading, found the terms Merxx or French Fit, and don’t know what you need? Every style of riding is different- in how you fit the bike to you, and the sizing of the bike itself. It’s more than just measuring your height, reach and inseam. With the help of Bike Fitting, you’ll be able to find the right fit for your frame size, style of riding, and your particular dimensions. Here ya’ go…..the location for everything fit related.
