Can my business partner unilaterally remove my name from the LLC? Can this partner return a truck to me that is not yet paid in full?

My friend and I started a trucking business in Davenport in 2021. I purchased a RAM 3500 for the business to use which is paid monthly by the business. I also took out a personal loan from my bank to put a big downpayment on the truck and to pay a full year of commercial insurance coverage. The load is also being paid monthly by the business. Most everything about the business is under my name. Now I believe that my business partner is looking forward to removing me from the business, including unilaterally removing my name from the LLC. Furthermore, my business partner has threatened to return the truck to me without being paid in full which will be harmful to me financially and my credit. I also contributed to acquirements of other assets in the business. So, what are my options here? Thank you.
